Python math - isfinite() Function
The Python math.isfinite() function is used to check if the argument is a finite number or not. It returns true if the argument is neither an infinity nor a NaN, else returns false.
Syntax
math.isfinite(x)
Parameters
x |
Required. Specify the value. |
Return Value
Returns true if the argument is neither an infinity nor a NaN, else returns false.
Example:
In the example below, isfinite() function is used to check if the argument is a finite number or not.
import math
print(math.isfinite(2))
print(math.isfinite(-2))
print(math.isfinite(1.5),"\n")
print(math.isfinite(float("nan")))
print(math.isfinite(float("inf")))
print(math.isfinite(float("-inf")))
The output of the above code will be:
True True True False False False
