    Note that as numbers in JavaScript are IEEE 754 floating point numbers with round-to-nearest-even behavior,
    these ranges, excluding the one for Math.random() itself, aren't exact, and depending on the bounds it's
    possible in extremely rare cases (on the order of 1 in 262) to calculate the usually-excluded upper bound.
