True and floor division, remainder, powers and round.

7 minutes3 games

Operator	Meaning	Example
`/`	true division (always float)	`7 / 2` → `3.5`
`//`	floor division	`7 // 2` → `3`
`%`	remainder	`7 % 2` → `1`
`**`	power	`2 ** 10` → `1024`
`abs()` / `round()`	absolute value / rounding	`round(3.14159, 2)` → `3.14`

Python

print(7 / 2, 7 // 2, 7 % 2, 2 ** 10)
print(round(3.14159, 2), abs(-8), max(4, 9, 2), min(4, 9, 2))

import math
print(math.sqrt(81), math.floor(4.7), math.ceil(4.2), math.pi)

print(10 / 3)
print(f"{10 / 3:.2f}")
print(1_000_000 + 1)

What's the output?

print(17 // 5, 17 % 5)

What will this code print?

What's the output?

print(6 / 2)

What will this code print?

Exercise
