Floating Point # in MIDP & CLDC...

What is way of using the floating point numbers in MIDP & CLDC?
MIDP and CLDC has no built in support for it.
Plz help me...

simple.... Don't :P
you've got fixed point libs available, but theyre not exactly fast.
It is possible to recompile the KVM and enable floating point support, but none of the embedded implementations have this support, so its a pointless excercise.
What do you need floating point for?

MIDP and floating-point numbers

Hiya,
I need to use floating numbers in a few occasions in a MIDP app that I'm programming at the moment. Whenever I do so though I get a nervous-breaking error at the pre-verification stage of the build. I am working with Wireless Toolkit 2.0 and the rror I get is:
Building "MyMIDlet"
Error preverifying class <ClassName>
ERROR: floating-point constants should not appear
com.sun.kvem.ktools.ExecutionException: Preverifier returned 1
Build failedI get this error whenever I use a floating-point varible or even whenever I compare something to a floating-point value.
It's got me really puzzled and I can't think of any way around the problem. Any help would be very much appreciated...
Thanks!

also WTK 2.1 (and CLDC 1.1I think ) does support FP. You think right, CLDC 1.1, that's when they added the floats (in theory a device could be MIDP 1.0 on top of CLDC 1.1, and it would also have floats). There's only one CLDC 1.1 device I've heard of: Nokia 6320.

Can I create a java app for my palm zire 71 that uses floating point calc

I am an eclipse user that is looking at studio creator 2 and was wondering if I could create a java app for my palm zire 71. I have read alot about no floating point support in midp... is that true for java on the palm? If so, how does one calculate with floats and doubles to do sqrt functions etc?
Thanks in advance for your time
Dean-O

I looked at netbeans and it does not support floating points in midlets. Not good for palm app if no floating point ability. J2ME supports floating point but in netbeans... is uses midlets and there are no floating points. Now what does one do? Not that dreaded C++
THanks in advance

Can anybody help me quick?

If the platform is CLDC 1.1 you can have floats. Run preverify to see the options. The cldc1.1 preverifier seems to have options to allow rejecting floats/doubles but the default seems to be to allow them.
Usage: preverify [options] classnames|dirnames ...
where options include:
-classpath <directories separated by ';'>
Directories in which to look for classes
-d <directory> Directory in which output is written (default is ./output/)
-cldc1.0 Checks for existence of language features prohibited
by CLDC 1.0 (native methods, floating point and finalizers)
-nofinalize No finalizers allowed
-nonative No native methods allowed
-nofp No floating point operations allowed
@<filename> Read command line arguments from a text file
Command line arguments must all be on a single line
Directory names must be enclosed in double quotes (")

"floating point constants should not appear"

when i compile my midlet using CLDC 1.0 the preverifier returns the error "floating point constants should not appear".. build failed.
does this mean i can't assign decimal numbers to variables?

Correct, those byte codes are not available on a CLDC 1.0 JVM. You have to use a CLDC 1.1 JVM.

No floating point?

Im told that j2ME can't perform floating-point! Is that true? Had anyone seen article regarding this? thans!

Hi,
this is defined in JSR for MIDP 1.0 (2.0 supports floats, if I'm not mistaken). You can download JSR 037 at http://www.jcp.org/aboutJava/communityprocess/final/jsr037/index.html.

SQL Loader and Floating Point Numbers

Hi
I have a problem loading floating point numbers using SQL Loader. If the number has more than 8 significant digits SQL Loader rounds the number i.e. 1100000.69 becomes 1100000.7. The CTL file looks as follows
LOAD DATA
INFILE '../data/test.csv' "str X'0A'"
BADFILE '../bad/test.bad'
APPEND
INTO TABLE test
FIELDS TERMINATED BY "," OPTIONALLY ENCLOSED BY '"'
Amount CHAR
and the data file as follows
"100.15 "
"100100.57 "
"1100000.69 "
"-2000000.33"
"-100000.43 "
the table defined as follows
CREATE TABLE test
Amount number(15,4)
) TABLESPACE NNUT050M1;
after loading a select returns the following
100.15
100100.57
1100000.7
-2000000
-100000.4
Thanks in advance
Russell

Actually if you format the field to display as (say) 999,999,999.99, you will see the correct numbers loaded via SQL Loader.

R6002 - floating point not loaded / C++ Runtime Error

Good Evening,
I have been having this problem with Adobe Bridge for a while and tonight sat down to try and solve it. Fresh version of Windows XP reinstalled all programs and this is still happening! Any Ideas?
This error only occurs with Adobe Bridge, I can load Photoshop etc.. all fine.
Error:
"Runtime Error!
Program: C:\ProgramFiles\Adobe\Adobe Bridge CS3\Bridge.exe
R6002
- floating point not loaded"
Here is a print screen..
http://images.unbrokenphotography.co.uk/BridgeError.jpg

Is there are answer to this problem? This error message is appearing on an entire lab full of computers. We are running Web Premium CS4
I have tried to reset the Bridge Preferences:
Hold down the Ctrl key and click on Bridge icon to start.
Should get a reset window with 3 options.
Choose the first option
I still get "Runtime Error! Program: C:\Prgram Files\Adobe\Adobe Bridge CS4\Bridge.exe R6002 -floating point support not loaded"

Invalid Floating Point Error

I have one Captivate 3 project published as a Stand Alone
project with Flash 8 selected. There are 36 slides, no audio, no
eLearning, SWF size and quality are high.
One person who runs this gets an "Invalid Floating Point"
error when he tries to run it the first time. He is running Windows
XP SP2, Firefox 3.0.4. and Flash Player 10.0.12.36. Other Captivate
projects I've created run fine for him. This one sometimes runs
after the first Error message.
Any thoughts on the cause and fix?
Thanks,
Janet

iMediaTouch probably doesn't support Floating Point formats - it certainly doesn't mention them in the advertising. Try saving your files as 24-bit PCMs, and they should import fine.

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.

Hi,
You'd better ask this question in ABAP forum http://forums.sdn.sap.com/forum.jspa?forumID=50 .

Conversion of a floating point type field

Hi,
I'm fetching field ATFLV from table AUSP for a particular value of ATINN.ATFLV is a floating point type field.
Can anyone please guide me as to how to convert this field(ATFLV) from floating point no. to a simple no.?
Helpful answers will be rewarded.
Regards,
Sipra

hi,
Do like this,
float f = 234.33;
int i = (int) f; // i has value 234.
reward points if helpful..

Maximum size of a floating-point number

Morning all,
Does anyone know what the maximum size of a floating point number can be under Solaris 8 running on
a V880?
Regards,
Richard Breckon

I'm not sure what you're asking.
The maximum size is 128 bits.
The maximum value is as given in /usr/include/float.h: 1.189731495357231765085759326628007016E+4932L

Check Floating Point Number

Hello All,
I am having some trouble checking the value of a field with Key Figure type Number with 8 byte floating point. I want to read that field and populate another field with an X if true. For example if that field is equal to 5,0000000000000000E+07 then i want to mark the other field with an 'X'.
The problem is in my code, how do i read that number in the fltp field, such as the number above. my code reads as follows for the 'X' field.
    if SOURCE_FIELDS-abc123 eq 5000000.
      RESULT = 'X'.
    endif.
Thanks everyone in advance

You don't need to worry about converting the code into standard format or floating, just implement your code as you want and it will automatically take care of the conversion. Basically 5,0000000000000000E+07 = 50,000,000.
thanks.

32 bit Floating Point

Hello,
Running FCP 5.1
Having audio sync issues and was double checking my settings.
Although the sequence presets are at 16 bit, they are showing up in the browser as 32bit Floating Point.
Any thoughts?
I generally capture now at 30 minute increments and actually have always had this issue. FCP 4.5 and 5.1
all settings are where they should be.
although I do notice, obviously when the device is off, the audio output defaults to 'default' not to firewire dv.
thanks
iMac intel Mac OS X (10.4.8)

Some more details please. What hardware device are you sourcing the audio clips from? The likely culprit is your capture settings. What preset are you using? Check Audio/Video Settings-Capture Presets and see if the preset you've selected records audio as 32 bit. It will say in the right column after you've selected your preset.
If it says 32 bit there, click Edit to get the Capture Preset Editor. Under Quicktime Audio Settings, the Format field should give you a selection of sample rates and possibly alternate bit depths. If your only choice is 32 bit, (as it is for me when I capture audio via my RME, 32 bit Integer in my case) then you'd be well served by bringing those files into Peak or Quicktime and saving them as 16 bit Integer files to match your sequence settings.
If you've imported these files into FCP from an audio editor that can create 32 bit floating point audio files, eg Kyma, Sequoia, Nuendo, etc. then the same advice applies. The 32 bit files are much larger than they need to be and may upset the apple cart (he he, pun) when pulled into a sequence with different settings. More cpu overhead for sure.
Let us know what you find.

How to make floating point division

I have tried many alternatives but i couldnt make any single floating point number printed to a page...
I am compiling the servlet with eclipse 3.2 without any error but the jsp page says java.lang.NoSuchFieldError: floatnumber even i have that variable...
i have tried double,float but both of them makes the error above...but i can print long as well.
can anyone teach me to divide 2 integer values and print the exact result like;
3 / 5 = 0.6

can anyone teach me to divide 2 integer values and
print the exact result like;
3 / 5 = 0.6
int a= 3, b= 5;
double result= ((double)a)/b;... or any valid variation thereof.
kind regards,
Jos
