bitLength

bitLength

> Functions

Returns the number of significant bits needed to represent the number x*, that is the position of the highest bit set to 1, plus one. Returns 0 when *x is 0.

For a positive number, the result equals floor(log2(x)) + 1. The function also works on big integers.

Parameters

• x : The integer whose bit length will be returned.

Return

• length : The number of bits needed to represent x*, or 0 if *x is 0.
