General description
The fabs() functions
calculate the absolute value of a decimal floating-point argument.
Notes:
- To use IEEE decimal floating-point, the hardware must have the Decimal Floating-Point Facility installed.
- These functions work in IEEE decimal floating-point format. See IEEE binary floating-point for more information
Returned value
Returns the absolute value of the decimal floating-point input.
Example
/* CELEBF75
This example illustrates the fabsd128() function.
