Decimal Number Validation.

Hi All,
I'm working on Interface currently where I need to load data from flat file to db. I use the sql loader to load the data, but before I saved the data I need to validate certain fields. How i can validate do decimal number validation. For an example, 1.11 is valid and 1.111 is invalid (2 decimal level). When i do the validation i need to check the field so it contains 2 decimal points only. If i contains 3 decimal point the data is invalid. Appreciate if anyone can help me with this. Thanks alot.

1. Will you want to load only valid data ??
2. Fail the load if one such invalid data found?
you need to use WHEN clause functionality in the sql loader - foe examples pls visit -
http://psoug.org/reference/sqlloader.html
WHEN clause shud look something like following -
WHEN LENGTH(substr(:columnname,INSTR(:columnname,1,'.')+1,LENGTH(:columnname))) <=2Using above will load only records having one or two digits after the dot [upto 2 decimal]
Assumption - Column name what ever you are choosing shud have only one decimal [one dot]in its designated start and end places.
Hope this helps..
[Untested]

Serial Number validation during Delivery Creation itself(PGI-system checks)

Process:
Sales Order PR(Purchase Order) GR( New Serial Numbers are created automatically or manually keyed in)
Once the Goods Receipt is received, we do the (SO) DELIVERYu2014SERIAL NUMBER ASSIGNMENT Post Goods Issue
Issue:
Current Serial Number Profile Management does not do a valid serial number check during DELIVERY CREATION where we do a SERIAL NUMBER ASSIGNMENT.
Only during POST GOODS ISSUE, the check happens for valid serial numbers; this is too late in the game for business as there is a time lag of 3 days from the DELIVERY CREATION and PGI.
Reason being--- We donu2019t check the following u201C Existing Stock Checku201D( which does a serial number validation during delivery creation as well)
SPRO>Plant Maintenance and Customer Service>Master Data in Plant Maintenance and Customer Service>Technical Objects>Serial Number Management>Define Serial Number Profiles
If we check this option, the business requirement to do a valid serial number check does happen during delivery creation, however we cannot create new serial numbers during Purchase Order- GOODS RECEIPT.
QUESTION:
Can we have the system check the valid serial numbers from stock during delivery creation and serial number assignment.
And Also create new serial numbers during Purchase Order- Goods Receipt.

Hi
1.In std SAP its not possible to check the serail number during Delivery creation, through enhancement it can be done.
2.During GR for PO serial numbers can be created.

How to convet a decimal number of in to base 64.

Hi friends,
my requirement is how to convet a decimal number of in to base 64.
ex:decimal number could be any type 1,1.2,-1,-1.2 etc
i found an API Base64.java but iam not able to use .
Please Help me out.

try this
Typecast your array of integers to Byte[] and use method byteArrayToBase64() as:
String encodeArray = Base64.byteArrayToBase64( new byte[]{ 3, 34, 116, 9 } );Also, browse the below link for more details

I can't use a decimal number in a update routine

Hi,
I want to use a decimal number in a udate routine (in a updating rule). I've a code similar to this:
IF COMM_STRUCTURE-/BIC/ZSATIAUX1 LT 1,5.
RESULT = 'GOOD'.
And when I save the routine I get the following error:
E:Comma without preceding colon (after IF ?).
The COMM_STRUCTURE-/BIC/ZSATIAUX1 field is numeric field with three decimal positions.
Can anybody tell me why I can't use decimals in my routine?
Thanks in advance.
Regards.

Hi,
Try following code:
Data: Val type COMM_STRUCTURE-/BIC/ZSATIAUX1 .
val = 1.5.
IF COMM_STRUCTURE-/BIC/ZSATIAUX1 LT val.
RESULT = 'GOOD'.
endif.

Comma or point in decimal number

Hi,
I wonder how to handle decimal number input from jsp page with comma or point. Is there a way to take care of this automatic so a comma get parsed to a point or vice versa.
Thanks in advance.

I don't know if it will be a comma or a dot that is inputed. My keyboard uses a comma on the numeric pad but if i change it to a US keyboard it will use dot instead so I can't tell what a user will input. And if I understand everything when java calculates a double it has to be with a dot, or am I completly wrong.
So with this in mind i decided to replace all dots with a comma and then parse it to a double with NumberFormat and do my calculation and then format it with NumberFormat again. This works fine and gives me a nice output if no one tries to input more than one point or comma.
I can't think of another way to do it so if this is completly wrong so please point me in the right direction.

How to convert fractional decimal number to hex number?

This question is not clear at all.
"Fractional decimal" is not a data type, but a way of formatting in readable form using numeric characters and a decimal separator.
Same to "hex number", but only for integers.
What do you mean by "convert"? Do you want to keep the value the same or retain the bit pattern of the numeric data type?
Hexadecimal is for integers. Are you talking about fixed point?
We clearly need significantly more information. What are the input and output data types? What are you actually trying to do?
Do you have an example input and corresponding output?

Is it a float or a double?
For a float, the decimal should be 4 bytes (small numbers like 1.1 start with the byte 0x40). Convert these 4 bytes to an int, using byte-shifting would probably be easiest.
int value = ((b3 << 24) + (b2 << 16) + (b1 << 8) + b0);//b# are bytesNow to convert it to a float, use
Float.intBitsToFloat(value);Now if you want double percision, You will have 8 bytes instead of 4, and need to be converted to a long instead of an int through byte-shifting. Then use Double.longBitsToDouble(long bits) to get the double

Program to convert binary to decimal number?

I only know how to do a program that converts only 4 numbers, but it to convert any amount of digits the number enters, I think you need to use a loop or something, but I'm not sure how. Could someone please help me? This is my code so far:
import javax.swing.JOptionPane;
public class bintodec {
     public static void main (String[] args) {
          String input;
          int number,digit1,digit2,digit3,digit4,result;
          input = JOptionPane.showInputDialog ("Enter a binary number.");
          number = Integer.parseInt(input);
          digit1 = ((number % 10000) - (number % 10000 % 1000)) / 1000;
          digit2 = ((number % 1000) - (number % 1000 % 100)) / 100;
          digit3 = ((number % 100) - (number % 100 % 10)) / 10;
          digit4 = (number % 10);
          result = (digit1 * 8) + (digit2 * 4) + (digit3 * 2) + (digit4 * 1);
          System.out.println ( "Binary number: " + input + "\nConverted Decimal Number: " + result);
          System.exit( 0 );
     } // main
} // bintodecany help is super-appreciated.

I am not sure if this will help you. Check it out, run it and let me know if it helped.

Use a For loop to index into the array, then use the Not Equal To Zero comparison to convert it to true/false. Then Index out of the For and use the Bool Array to Int from the boolean pallete.
Here is an example in 8.2

We can't add a decimal number column with the create table forms

In the version 4, we can't add a decimal number column with the create table forms.

In the GUI, I found the following column (I translate from french to english): PK, Name, Data_type, lenght, not null, default, comments.
In the lenght field, if I enter 9,3 to have a NUMBER(9,3), I have a message saying that the number must be an integer.
