##

gentype `fmax` gentypex gentypey gentypef `fmax` gentypefx float y gentyped `fmax` gentypedx double y

##

gentype `fmax` (gentype `x`, half `y`) // if half extension enabled

## Description

Returns `y` if `x` is less than `y`, otherwise it returns `x`. If one argument is a NaN, `fmax()` returns the other argument. If both arguments are NaNs, `fmax()` returns a NaN.

## Notes

fmin and `fmax` behave as defined by C99 and may not match the IEEE 754-2008 definition for `minNum` and `maxNum` with regard to signaling NaNs. Specifically, signaling NaNs may behave as quiet NaNs.
