ARTICLE

Operations with Floating Point Numbers
Class CL_ABAP_MATH contains methods and constants for operations with floating point numbers.

Rounding binary floating point numbers
Method ROUND_F_TO_15_DECS rounds a
binary floating point number arithmethically to 15 decimal places.

Operations with decimal floating point numbers

Method GET_SCALE gets the scaling of a decimal floating point number .

Method GET_NUMBER_OF_DIGITS gets the

precision of a decimal floating point number
.

The method NORMALIZE gets a normalized floating point number. This means that the scaling and precision of an input value are changed so that the mantissa has no trailing zeros.

Method GET_SCALE_NORMALIZED returns the

scaling of a decimal floating point number
. If the input value has decimal places, the return code is the number of decimal places without trailing zeros.

The method GET_MAX_DB_VALUE returns the maximum value of a number of the type DF16_DEC or DF34_DEC on the database.

The method GET_DB_LENGTH_DECS returns the length and number of decimal places of a number of the type DF16_DEC or DF34_DEC

on the database.

Note
The rounding functions round
and rescale can be used to round and rescale decimal floating point numbers.
