How to Move Decimals to Comp-5 in COBOL

While moving decimal value to Comp-5, just you need to consider these since it stores only integer portion, and ignores decimal portion.

Suppose, you have defined a field with PIC 9(07)v99 and you moved value from this data type to comp-5.

COBOL Example: How to use COMP-5.

01 My-data     PIC 9(07)v99 value 1234567.10.
01 Out-data    comp-5 or S9(07)v99 Comp-5.
   MOVE My-data   to  Out-data.

The result will be: 1234567


The key point I want to share is Comp-5 stores only integer part and truncates decimal part.

Note: So, you cannot use comp-5 as S9(07)v99, but you can use as S9(09).

More details of COMP-5

  • Comp-5 stores the data in the form of Binary ( because of binary it doesn’t support decimals)
  • It has boundaries. It stores as 2/4/8 bytes internally
  • S9(1) to S9(4) => 2 bytes(half)
  • S9(5) to S9(9) ==> 4 bytes(full)
  • S9(10) to S9(18) ==> 8 bytes(double)
  • With or without ‘S’ you can define the Comp-5 data types
