Python math.frexp()

In Python, the math.frexp() method calculates the mantissa and the exponent of a given number. The mathematical formula that is used in this method is n = m * 2^e, where n is the given number, m is the mantissa, and e is the exponent. The method returns the mantissa and the exponent in a tuple (m, e).

Syntax

math.frexp(x)

• x: The number whose mantissa and exponent are to be calculated. If the input is not a number, the method returns a TypeError.

Example

The following example demonstrates the usage of the math.frexp() method:

import math

# Calculating the mantissa and the exponent of different numbers
print(math.frexp(10))
print(math.frexp(20))
print(math.frexp(30))
