Functionality

This function is used to reduce the number of decimals places associated with a field and round the value either up or down in the process.

Example

The input parameter (VALUE_IN) is passed in as type P (Packed decimal) with 5 decimals and contains the value '12.02455'. Parameter CONV_DEC contains the value '2', which signifies the number of decimals the value in VALUE_IN needs to be converted to whilst rounding, before placing the result in parameter VALUE_OUT.

If the value in VALUE_IN was simply moved to a field with 2 decimals, then the value would be incorrectly rounded to '12.02'. This problem is actually a limitation of the MOVE command, in that it only looks at one addition decimal point when rounding (In this case, it looks at the '4' in '12.02455' and ignores the subsequent digits).

This function however, performs the rounding between fields with a varying number of decimals correctly. After executing this function, the resulting value in parameter VALUE_OUT would be '12.03'.
