Python isinf

The Python isinf function is a Mathematical function, which checks whether the given value is an infinite number or not. If it is an infinite number, then Python math.isinf returns True otherwise, False.

The syntax of the isinf in Python Programming Language is as shown below

math.isinf(value)

Python isinf example

In this example, we are using the isinf function on both positive and negative numeric and decimal values. We have also used math.pi inside this isinf function.

import math
 
print(math.isinf(10))
 
print(math.isinf(0.00))
 
print(math.isinf(-200))
 
print(math.isinf(-4.0002))
 
print(math.isinf(math.pi))

OUTPUT

In this isinf example, we are passing the infinity, NaN(not a number) values as the function arguments.

import math
 
print(math.isinf(0/1))
 
print(math.isinf(0.00/1))
 
print(math.isinf(float('NaN')))
 
print(math.isinf(float('inf')))
 
print(math.isinf(float('-inf')))
