Integer and float numbers - Learn Python 3

7/10. Math module

Python has a ton of functions for calculations with floats. Most of them can be found in the math module.

To use this module, you need to import it first by writing the following instruction at the beginning of your program:

import math

For example, if we want to find the ceiling value for x — the smallest integer not less than x — we call the corresponding function from the math module: math.ceil(x).

Instructions

Click "Run" to see what happens in output!

import math

x = math.ceil(4.2)
print(x)
print(math.ceil(1 + 3.8))
