clamp

Description#

Clamp a number into the inclusive range [min, max]. null or undefined bounds read as -Infinity / +Infinity respectively, so either side can be left open. NaN value propagates and is returned unchanged. A NaN bound behaves like an open bound (every comparison against NaN is false, so that side never clamps) - pass-through, not an error. When the bounds invert (min > max after coercion), min wins and the returned value is min.
