Floating point to Date conversion

Do any Function module is available for converting the floating point value into Date.

hi,
do this way ...
DATA : p_float TYPE f,
           p_date LIKE cawn-atwrt,
           p_flt LIKE cawn-atflv,
           p_dt LIKE sy-datum.
p_float = '2.006123100000000E+07'.
p_flt = p_float.
CALL FUNCTION 'CTCV_CONVERT_FLOAT_TO_DATE'
EXPORTING
    float = p_flt
IMPORTING
    date = p_date.
WRITE : p_date TO p_dt DD/MM/YYYY.
WRITE : p_dt.

Floating point to binary conversion

Hi
I need to convert a floating point decimal number to bits.
Eg. 0.000532 to be converted to binary(bits).
How do I do this?

Now if I convert that decimal number to bits(in
the usual method of dividing by 2),will that be the
exact binary representation of the floating point
decimal number?You have the same bit pattern in both cases. In one it's held in a double and will be interpreted as a floating point number according to the IEEE 754 representation. In the other it's held in a long and will be interpreted according to the two's complement representation. But it's the same bitpattern.
Note that Long has a toString method which allows you to convert the long to a String. The radix in your case is 2 for binary.

Floating point to time conversion

Hi all,
I need to convert floating point value to time.Any help would be gr8

Hai,
Define two variables,one as float & another one as time take a & b.After assigning values to a,assign a to b.Then write b.The float value will be converted into time format.

Pack and Floating Point Data Type in ABAP

Dear All,
I am new to ABAP. Started with data types. Came across pack and floating point.
Please let me know what PACK and Floating Point stands for with few examples and the main difference between them.

Precision loss - conversions between exact values and floating point values

Hi!
I read this in your SQL Reference manual, but I don't quite get it.
Conversions between exact numeric values (TT_TINYINT, TT_SMALLINT, TT_INTEGER, TT_BIGINT, NUMBER) and floating-point values (BINARY_FLOAT, BINARY_DOUBLE) can be inexact because the exact numeric values use decimal precision whereas the floating-point numbers use binary precision.
Could you please give two examples: one where a TT_TINYINT is converted to a BINARY_DOUBLE and one when a TT_BIGINT is converted into a DOUBLE, both cases give examples on lost precision? This would be very helpful.
Thanks!

Floating point conversation

Dear all,
    In a particular filed i entered value as 60.800 kg. But when i try to pick the value   i found that the value is stored in floating pont format ie 6.080000000000e+00 . Actually i need it in integer format .Is any function module available to convert floating point to integer.
Regards
Mahesh V

Why use a function module?
DATA: l_val_int type i,
      l_val_flt type f,
      l_val_pck type p decimals 2.
l_val_flt = '6.080000000000e+00'.
l_val_int = l_val_flt.
l_val_pck = l_val_pck.

Floating point format conversions

Hi All,
I have a binary file that has 8 byte floats in it written in VAX D floating point format. It also has 4 byte integers in it. I have to read this file on a Sun Sparc. To get the correct value of the integers I just swap the bytes around and write out the int value, so bytes 0123 get rearranged to be 3210 and then I use that as my int. I tried that with the doubles, reorder bytes 01234567 to 76543210 and then write out the double value but I don't get the value that was stored.
I read 8 bytes from the file, I'm supposed to get 512.0 but I get garbage.
The hex dump of the file shows: 0045 0000 0000 0000
I can't come up with a way to turn that into 512.0
Another one is 360448.0 with hex dump: b049 0000 0000 0000
Can anyone show me how to manipulate these bits/bytes to get the correct values?
Thanks

Hi Legosa,
Thanks for looking for a solution for me. The linkhttp://nicmos2.as.arizona.edu/thompson/kfocas/vax2sun.c
has a C implementation of exactly what I need and has saved me a lot of time and work. Translation to Java will have to use bit shifting I think, the C unions make for a nice implementation.
I also have to read PC and Cray generated files on my Sun.
I have found that, like the Vax, Intel x86 including pentium are all little endian and use IEEE so I'm guessing that I just have to do the byte swapping to translate from PC to Sun.
Crays are Big endian so I don't need byte swapping but I do need to do some manipulation of the exponent and the mantissa.
Do you know where I might find code that others have done for PC to Sun and Cray to Sun conversions of integers, floats and doubles?
BTW, for those who may read this later, the solution in vax2sun.c isn't quite right, the author forgot to use the least significant 32 bits and lost 3 bits in the middle but it is very close. To make it closer you have to change the vax2sun.c code a little.
Replace mantissa and lomant with
In union ieeebuf
int mantissa1:20
int mantissa2:3
int mantissa3:29
In union vaxbuf
int mantissa1:20
int mantissa2:3
int mantissa3:29
int lost_bits:3
In the code replace d.mantissa = v.mantissa/8 with:
d.mantissa1 = v.mantissa1
d.mantissa2 = v.mantissa2
d.mantissa3 = v.mantissa3
My few tests showed this gave very good results. The lost_bits are lost because ieee needs 3 more bits for its exponent so it doesn't have room for all of the vax mantissa bits. A little bigger range means a little less precision.

Profibus data type converting to floating point

Hi,
Is there an efficient way to convert the incoming data to the floating point in the NI cRIO Profibus system?
1) The system is : NI cRIO 9068 Controller with Comsoft profibus slave module. The lavview we are using is 2013.
2) We are using profibus slave example and are able to see a array of unsigned 8 bit data. Please see the Output data shown in the attachement.
3) On the other side of profibus system, thrid party profibus master are converting floating points and tranmit the converted data to NI profibus slave.

If it's just a matter of converting data types once you have the data in LabVIEW, you can always manually scale and convert the data using the arithmetic functions and the "To Double Precision Float" or "To Single Precision Float" functions. You just have to know what floating point value the unsigned byte integer corresponds to. Is that what you're asking?
If you're asking for a way to this inherently with the Profibus functions, I'm afraid I can't be of much help...

Inline functions in C, gcc optimization and floating point arithmetic issues

For several days I really have become a fan of Alchemy. But after intensive testing I have found several issues which I'd like to solve but I can't without any help.
So...I'm porting an old game console emulator written by me in ANSI C. The code is working on both gcc and VisualStudio without any modification or crosscompile macros. The only platform code is the audio and video output which is out of scope, because I have ported audio and video witin AS3.
Here are the issues:
1. Inline functions - Having only a single inline function makes the code working incorrectly (although not crashing) even if any optimization is enabled or not (-O0 or O3). My current workarround is converting the inline functions to macros which achieves the same effect. Any ideas why inline functions break the code?
2. Compiler optimizations - well, my project consists of many C files one of which is called flash.c and it contains the main and exported functions. I build the project as follows:
gcc -c flash.c -O0 -o flash.o     //Please note the -O0 option!!!
gcc -c file1.c -O3 -o file1.o
gcc -c file2.c -O3 -o file2.o
... and so on
gcc *.o -swc -O0 -o emu.swc   //Please note the -O0 option again!!!
mxmlc.exe -library-path+=emu.swc --target-player=10.0.0 Emu.as
or file in $( ls *.o ) //Removes the obj files
    do
        rm $file
    done
If I define any option different from -O0 in gcc -c flash.c -O0 -o flash.o the program stops working correctly exactly as in the inline funtions code (but still does not crash or prints any errors in debug). flash has 4 static functions to be exported to AS3 and the main function. Do you know why?
If I define any option different from -O0 in gcc *.o -swc -O0 -o emu.swc the program stops working correctly exactly as above, but if I specify -O1, -O2 or O3 the SWC file gets smaller up to 2x for O3. Why? Is there a method to optimize all the obj files except flash.o because I suspect a similar issue as when compilling it?
3. Flating point issues - this is the worst one. My code is mainly based on integer arithmetic but on 1-2 places it requires flating point arithmetic. One of them is the conversion of 16-bit 44.1 Khz sound buffer to a float buffer with same sample rate but with samples in the range from -1.0 to 1.0.
My code:
void audio_prepare_as()
    uint32 i;
    for(i=0;i<audioSamples;i+=2)
        audiobuffer[i] = (float)snd.buffer[i]/32768;
        audiobuffer[i+1] = (float)snd.buffer[i+1]/32768;
My audio playback is working perfectly. But not if using the above conversion and I have inspected the float numbers - all incorrect and invalid. I tried other code with simple floats - same story. As if alchemy refuses to work with floats. What is wrong? I have another lace whre I must resize the framebuffer and there I have a float involved - same crap. Please help me?
Found the floating point problem: audiobuffer is written to a ByteArray and then used in AS. But C floats are obviously not the same as those in AS3. Now the floating point is resolved.
The optimization issues remain! I really need to speed up my code.
Thank you in advice!

Dear Bernd,
I am still unable to run the optimizations and turn on the inline functions. None of the inline functions contain any stdli function just pure asignments, reads, simple arithmetic and bitwise operations.
In fact, the file containing the main function and those functions for export in AS3 did have memset and memcpy. I tried your suggestion and put the code above the functions calling memset and memcpy. It did not work soe I put the code in a header which is included topmost in each C file. The only system header I use is malloc.h and it is included topmost. In other C file I use pow, sin and log10 from math.h but I removed it and made the same thing:
//shared.h
#ifndef _SHARED_H_
#define _SHARED_H_
#include <malloc.h>
static void * custom_memmove( void * destination, const void * source, unsigned int num ) {
void *result;
__asm__("%0 memmove(%1, %2, %3)\n" : "=r"(result) : "r"(destination), "r"(source), "r"(num));
return result;
static void * custom_memcpy ( void * destination, const void * source, unsigned int num ) {
void *result;
__asm__("%0 memcpy(%1, %2, %3)\n" : "=r"(result) : "r"(destination), "r"(source), "r"(num));
return result;
static void * custom_memset ( void * ptr, int value, unsigned int num ) {
void *result;
__asm__("%0 memset(%1, %2, %3)\n" : "=r"(result) : "r"(ptr), "r"(value), "r"(num));
return result;
static float custom_pow(float x, int y) {
    float result;
__asm__("%0 pow(%1, %2)\n" : "=r"(result) : "r"(x), "r"(y));
return result;
static double custom_sin(double x) {
    double result;
__asm__("%0 sin(%1)\n" : "=r"(result) : "r"(x));
return result;
static double custom_log10(double x) {
    double result;
__asm__("%0 log10(%1)\n" : "=r"(result) : "r"(x));
return result;
#define memmove custom_memmove
#define memcpy custom_memcpy
#define memset custom_memset
#define pow custom_pow
#define sin custom_sin
#define log10 custom_log10

It still behave the same way as if nothing was changed (works incorrectly - displays jerk which does not move, whereby the image is supposed to move)
As I am porting an emulator (Sega Mega Drive) I use manu arrays of function pointers for implementing the opcodes of the CPU's. Could this be an issue?
I did a workaround for the floating point problem but processing is very slow so I hear only bzzt bzzt but this is for now out of scope. The emulator compiled with gcc runs at 300 fps on a 1.3 GHz machine, whereby my non optimized AVM2 code compiled by alchemy produces 14 fps. The pure rendering is super fast and the problem lies in the computational power of AVM. The frame buffer and the enulation are generated in the C code and only the pixels are copied to AS3, where they are plotted in a BitmapData. On 2.0 GHz Dual core I achieved only 21 fps. Goal is 60 fps to have smooth audio and video. But this is offtopic. After all everything works (slow) without optimization, and I would somehow turn it on. Suggestions?

Byte Order for Floating Point Types

I need to send an array of floating point values from an x86 C++ application to a Java application. I am using a socket to transfer the data. What, if anything, do I have to do about preserving the correct byte order?

Probably nothing.
If you do end up having a problem, look at the java.nio package. Specfically, java.nio.ByteOrder, and java.nio.Double/FloatBuffer.
To be completely safe, I think I'd probably send an enum in some kind of header that indicates what byte order your C++ is sending and use the *Buffer classes to automatically handle the conversion.

Export to .exr / .hdr / floating point format from ACR?

Hi!
Context is that I'm doing HDRI images for rendering so dynamic range is the most important aspect.
I searched hard but didn't found a way to export from ACR into a floating point format which is very very very annoying because if you export as 16bit tiff it will obviously clip whatever values you have in your raw file. I can load the raw / dng files directly into Photomatix / Oloneo but then I'm losing any kind of Camera Profile / Distortion profile embedded with them.
Oh and I don't want to use Photoshop to Merge the HDRI files because I want to have control over the deghosting and various other alignement related stuff. I'm really searching for a .dng / .raw to .exr conversion.
Any ideas?
KS

I would benefit from first class raw demosaicing, noise reduction, undistortion, optional color profiling, etc... before sending that to merging in whatever software that is not the specialty to do what ACR does perfectly
Getting linear data out would be the step after all the ones I described and I wouldn't change any exposure, recovery, black level, tone curve, etc ... related options so that the HDRI merge is predictable. That's where the problem resides.
Lets say you have a photo with a bright sky, you load it in ACR, with everything to zero. Your sky is white and burnt ( But you actually have data from the raw file because you have checked it by changing the exposure compensation to -5 ) If you export the image as is without the exposure compensation, the sky data is clipped once casted to integer.
If you export it with the exposure compensation, the HDRI merge will be very very bad because the software will have an image with the data where the exposure has been shifted but still exhibit the exif data from the original file.
Of course you can merge with the tiff without the compensation and rely on a faster exposure to fill the missing data, it works but when you hit your latest fast exposure and you see that you would be able to pump even more dynamic range from it but that ACR clipped the data it's very frustrating.
I now hope it's crystal clear and why I would like to get a linear exr output I can also upload a raw file somewhere for people having trouble understanding the issue.
In the best case scenario Adobe will provide a solution, but if it happens it will not be before a while, in the worst case there won't be any solutions at all. With that in mind I wrote a Python script that generates for me the tail exposures for my bracketing sequences and modify accordingly the exif data.
My workflow is the following for now:
- Dump raw images from camera.
- Apply neutral preset, noise reduction on all the raw files.
- Praise Adobe for ACR.
- Launch the Python script that:
     - Generates a subfolder where all the raw and xmp files are copied.
     - Images are renamed reordered by their exposure time.
     - The tail exposure is duplicated 3 times.
     - The xmp files are updated with exposure compensation ( -1, -3, -5 ). Now I get the dynamic range.
     - The raw files exif data is altered to reflect the exposure compensation.
- Load the new raw files from the subfolder and convert them to tif.
- Rant against Adobe
- Merge to HDRI with my proper dynamic range.

Analog data to digital data conversion in labwindows

Hi
Is there any library function available in Labwindows for converting Analog data to Digital Data..
Thank You

shoukat,
could you please provide some more information about the background of this question? Is there any link to motion control (this is the Motion Control forum)?
I don't understand exactly, what you are looking for. All data that you use in a programming environment are digital data - regardless of the data type. Are you looking for a data conversion from floating point to binary (e. g. a boolean array) or are you looking for data acquisition hard- and software?

GL Data Conversion from Legacy to Oracle EBS

Hi All,
I am tasked with converting legacy data into GL. I have worked on other conversions like supplier, AR and AP conversions but never worked on GL conversion, so I don't know how and where to start, what are the pre-requisites for entering data into gl_interface table how to ensure that data is correct in the .csv file etc.
Kindly request you all to guide me in right direction. Hope to hear from you all very soon!!! :)
Regards

Hi,
When you talk about GL-Data it is the trial balance to be loaded from legacy to oracle applications.
You can use Web-ADI to upload it ,the check list are
The balance for each account comibnation in the legacy system to be mapped to GL-Oracle code combination balance
With respect to open AR, AP Invoices if the invoices are converted using a control account for migration in GL then
the the balance transfered from AP,AR need not be reversed in GL from the source receivables and payables.
In case if the same account combination are for migrating the balances from AP,AR to GL ..Then the balances transferred from AP,AR should be reversed ..so that it does not affect the TB-GL-Balance
Finally ensure that the balance for the TB-tallys with your legacy system and upload it using Web-ADI ,import and
review and post it.
Hope this points helps your GL-Data conversion.
