Python cmath - isfinite() Function
The Python cmath.isfinite() function returns True if both the real and imaginary parts of a given complex number are finite, and False otherwise.
Syntax
cmath.isfinite(x)
Parameters
x |
Required. Specify the value. |
Return Value
Returns true if both the real and imaginary parts of the argument are finite, and false otherwise.
Example:
In the example below, isfinite() function is used to check if the argument is a finite number or not.
import cmath
print(cmath.isfinite(2 + 2j))
print(cmath.isfinite(-2))
print(cmath.isfinite(1.5j),"\n")
print(cmath.isfinite(float("nan")))
print(cmath.isfinite(float("inf")))
print(cmath.isfinite(float("-inf")))
The output of the above code will be:
True True True False False False
