Working with numbers in Python

Integer and float arithmetic, and the operators that differ.

minutes = 947
hours = minutes // 60
remainder = minutes % 60
both = divmod(minutes, 60)

price = 19.99
tax = price * 0.0825
rounded = round(price + tax, 2)

big = 2 ** 32
ratio = 7 / 2
floored = 7 // 2

How it works

1. Splits minutes into hours with floor division // and %.
2. divmod returns quotient and remainder at once.
3. Rounds a float result to 2 places with round.
4. / always gives a float; // keeps integers whole.
