answer python bit_length

python bit_length

Comment

// Returns the number of bits necessary to represent an integer in binary, 
// excluding the sign and leading zeros.

// If x is nonzero, then x.bit_length() is the unique positive integer k 
// such that 2**(k-1) <= abs(x) < 2**k. Equivalently, when abs(x) is small 
// enough to have a correctly rounded logarithm, then k = 1 + int(log(abs(x), 2)).
// If x is zero, then x.bit_length() returns 0.

// In python 2.7+ there is a int.bit_length() method:

a = 100
a.bit_length()
7
