Math.MAX_RANDOM_BITS

[Rudxain]

This constant is defined as "the maximum number of bits after the radix-point, that Math.random could return". The use-case is to predict how much "entropy-per-call" can be extracted from Math.random. This is especially useful when multiplying the returned number by something close to Number.MAX_SAFE_INTEGER, as it can be used to predict how much bias there will be.

Its value is expected to be either 52 or 53, as 52 is the mantissa-size, and 53 includes the implicit-bit. The value is implementation-dependent, and this is the main reason why this "constant" should exist, to prevent code from guessing entropy in unreliable ways
