saturate

Clamps to [0, 1]: float, float64, and each component of a vector. A NaN is returned as it is.

assert(saturate(1.5) == 1 && saturate(-0.5) == 0 && saturate(0.25) == 0.25);
assert(saturate(xyz(2, -1, 0.5)) == xyz(1, 0, 0.5));

saturate :: (f: float) -> float

saturate :: (f: float64) -> float64
