General description
The fmax() family of
functions determine the maximum numeric value of their arguments.
NaN arguments are treated as missing data. If one argument is a NaN
and the other numeric, then the numeric value will be chosen.
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 Decimal Floating-Point" for more information.
Returned value
If successful, they return the maximum numeric value of their arguments.
Example
/* CELEBF79
This example illustrates the fmaxd128() function.
