Python Math Library | exp () method

Python has a math library and has many functions related to this. One of these functions is exp () . This method is used to compute the degree of e, i.e., e ^ y, or we can say exponential in y. The value of e is approximately 2.71828 ... ..

Syntax: math.exp (y)

Parameters:
y [Required] - It is any valid python number either positive or negative.
Note that if y has value other than number then its return error.

Returns: Returns floating point number by calculating e ^ y.

Code # 1:

# Python3 demo code
# exp () work

import math 

 
# value initialization

test_int = 4

test_neg_int =   - 3

test_float = 0.00

 
# checking exp () values ​​
# with different numbers

print (math.exp (test_int))

print (math.exp (test_neg_int))

print (math.exp (test_float))

Exit:

 54.598150033144236 0.049787068367863944 1.0 

Code # 2:

# Python3 demo code
# exp () work

import math 

 
# checking exp () values ​​
# with embedded numbers

print (math.exp (math.pi))

print (math.exp (math.e))

Output:

 23.140692632779267 15.154262241479262 

Code # 3: TypeError

# Python3 demo code
# exp () work

import math 

 
# line check

print (math.exp ( "25" ))

Exit:

 Traceback (most recent call last): File "/home/c7ae4f1bef0ed8c7756b3f55e7d2ce81.py", line 6, in print (math.exp ("25")) TypeError: a float is required
