General description

The fmin() family of functions determine the minimum 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.
Note: The following table shows the viable formats for these functions. See IEEE binary floating-point for more information about IEEE Binary Floating-Point.
Function Hex IEEE
fmin X X
fminf X X
fminl X X
Restriction: The fminf() function does not support the _FP_MODE_VARIABLE feature test macro.

Returned value

If successful, they return the minimum numeric value of their arguments.
