Python math.isfinite() Method

❮ Math Methods

Example

Check whether a value is finite or not:

# Import math Library
import math

# Check whether some values are finite
print (math.isfinite (56))
print (math.isfinite (-45.34))
print (math.isfinite (+45.34))
print (math.isfinite (math.inf))
print (math.isfinite (float("nan")))
print (math.isfinite (float("inf")))
print (math.isfinite (float("-inf")))
print (math.isfinite (-math.inf))
