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 aTypeError
.
Example
The following example demonstrates the usage of the math.frexp()
method:
import math# Calculating the mantissa and the exponent of different numbersprint(math.frexp(10))print(math.frexp(20))print(math.frexp(30))
The above code produces the following output:
(0.625, 4)(0.625, 5)(0.9375, 5)
