The math.frexp() function returns the mantissa and the exponent of the input number in base 2.

math.frexp(x)

`x`	An integer or a float.

The function returns the mantissa and exponent of x as a pair (m, e), where m is a float with an absolute value between 0.5 (inclusive) and 1.0 (exclusive), and e is an integer such that x == m * 2**e. Where , m is the mantissa and e is the exponent.

import math 

print(math.frexp(0))
print(math.frexp(0.5))
print(math.frexp(4))
print(math.frexp(-9))
print(math.frexp(10))
print(math.frexp(-44))

A TypeError is raised if x is not an integer or a float.
