General description
The fdim functions
compute the positive difference between x and y.
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
The fdim functions return the positive difference between x and y.
Example
/* CELEBF76
This example illustrates the fdimd32() function.
