System Class CL_ABAP_MATH ITOC
Constants for Minimum and Maximum Values The class CL_ABAP_MATH contains constants with the limits of the value ranges built-in numeric types.
ABAP_EXAMPLE_VX5 Display of the minimum and maximum values of numeric types. ABEXA 01028 ABAP_EXAMPLE_END
Operations with Floating Point Numbers The class CL_ABAP_MATH contains methods for operations with floating point numbers.
Rounding Binary Floating Point Numbers The method ROUND_F_TO_15_DECS rounds a binary floating point number to 15 places using commercial rounding.
Latest notes: Commercial rounding to 15 digits can also be achieved using the built-in function round, the result of which, however, has the decfloat34 type. NON_V5_HINTS ABAP_HINT_END
ABAP_EXAMPLE_VX5 The example shows how rounding errors in the output formatting of binary floating point numbers can be prevented by two-step rounding using the method ROUND_F_TO_15_DECS. Instead of the method call, the function call round( val = float dec = 15 ) can be used here. ABEXA 01029 ABAP_EXAMPLE_END
Operations with Decimal Floating Point Numbers
The method GET_SCALE returns the scaling of a decimal floating point number.
The method GET_NUMBER_OF_DIGITS returns the precision of a decimal floating point number.
The method NORMALIZE returns 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.
The method GET_SCALE_NORMALIZED returns the scaling of a normalized decimal floating point number. If the input value has decimal places, the return value 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.
Latest notes: NON_V5_HINTS The rounding functions round and rescale can be used to round and rescale decimal floating point numbers. ABAP_HINT_END
ABAP_EXAMPLE_VX5 Display of the scaling and precision of a decimal floating point number. ABEXA 01030 ABAP_EXAMPLE_END
