ABAP Rounding function

ABAP Rounding function

There are a number of function methods for processing data in ABAP , involving rounding of two (and possibly more):ROUND and hr_nz_rounding_decimals

The former is located in the basis function development package Szme inside, in the standard for the calculation of units of measurement;

The latter is mainly used in the HR module, located in the PB43 development Package, processing the master data in the HR module.

hr_nz_rounding_decimals The function can enter a numeric value directly and then enter a decimal point to be preserved in the conv_dec parameter to output.

The ROUND function is somewhat flexible and can be controlled up or down by the sign parameter (' + ', '-').

For example:

Enter 88.54350, if sign = ' + ', retain 2 decimal places, will get: 88.55000; if sign = '-', you will get: 88.54000

Input-88.54350, if sign = ' + ', retains 2 decimal places, will get:-88.54000; if sign = '-', you will get:-88.55000
