The math module in Python

Exact integer maths, careful float maths, and the constants.

import math

print(math.pi, math.tau)
print(math.isclose(0.1 + 0.2, 0.3), math.isclose(0.1 + 0.2, 0.3, abs_tol=1e-9))
print(math.floor(2.7), math.ceil(2.1), round(2.5), round(3.5))
print(math.gcd(84, 36), math.isqrt(50), math.comb(10, 3))
print(math.hypot(3, 4), math.log(math.e), math.log10(1000))
print(math.inf > 1e308, math.isnan(float("nan")))

How it works

1. isclose is how you compare floats.
2. comb and factorial are exact for integers.
3. hypot, gcd and isqrt save you writing them.
