Sometimes, we want to check if a float value is a whole number with Python.

In this article, we’ll look at how to check if a float value is a whole number with Python.

How to check if a float value is a whole number with Python?

To check if a float value is a whole number with Python, we can use the float’s is_integer method.

For instance, we write:

print((1.0).is_integer())
print((1.5).is_integer())

We call is_integer on 2 floats and print out the values.

Since 1.0 is an integer, the first print will print True.

And since 1.5 isn’t an integer, the 2nd print will print False.

Conclusion

To check if a float value is a whole number with Python, we can use the float’s is_integer method.
