Python math.exp() method

math.exp() method is a library method of math module, it is used to get the number in exponential form, it accepts a number and returns the number in the exponential format (if the number is x, it returns e**x.

Note: If anything is passed except the number, the method returns a type error, "TypeError: a float is required".

Syntax of math.exp() method:


Parameter(s): n – an integer or a float number.

Return value: float – it returns a float value that is an exponential form of the number n.


    a = 111.111

    # function call


Python code to demonstrate example of math.exp() method

# Python code demonstrate example of 
# math.exp() method
import math

# numbers

a = 0
b = 245
c = -102.34
d = 111.111
e = -123.456

# printing values in exp format
print("exp(a): ", math.exp(a))
print("exp(b): ", math.exp(b))
print("exp(c): ", math.exp(c))
print("exp(d): ", math.exp(d))
print("exp(e): ", math.exp(e))


exp(a):  1.0
exp(b):  2.5243412626998188e+106
exp(c):  3.583461328080821e-45
exp(d):  1.7984326512709283e+48
exp(e):  2.4195825412645934e-54
