Numbers and types

Python has several kinds of numbers. int is a whole number, float a decimal number. Regular division / always gives a float, while // rounds down to an integer and % gives the remainder. type(x) shows a value's type.

a\,/\,b

regular division, always float

a\,/\!/\,b

integer division, rounded down

a \% b

remainder after integer division

Symbols

a,\ b

the numbers being divided

Example

7 // 2 gives 3, and 7 % 2 gives 1, since $7 = 3\cdot 2 + 1$ .

7 / 2 gives 3.5.

// and % are linked: a == (a // b) * b + a % b.
