# Integer division in Python 2 and Python 3

## Question:

How can I divide two numbers in Python 2.7 and get the result with decimals?

I don’t get it why there is difference:

in Python 3:

```
>>> 20/15
1.3333333333333333
```

in Python 2:

```
>>> 20/15
1
```

Isn’t this a modulo actually?

## Answers:

In Python 3, `/`

is float division

In Python 2, `/`

is integer division (assuming `int`

inputs)

In both 2 *and* 3, `//`

is integer division

(To get float division in Python 2 requires either of the operands be a float, either as `20.`

or `float(20)`

)

In Python 2.x, make sure to have at least one operand of your division in `float`

. Multiple ways you may achieve this as the following examples:

```
20. / 15
20 / float(15)
```

In Python 2.7, the `/`

operator is integer division if inputs are integers.

If you want float division (which is something I always prefer), just use this special import:

```
from __future__ import division
```

See it here:

```
>>> 7 / 2
3
>>> from __future__ import division
>>> 7 / 2
3.5
>>>
```

Integer division is achieved by using `//`

, and modulo by using `%`

:

```
>>> 7 % 2
1
>>> 7 // 2
3
>>>
```

As commented by `user2357112`

, this import has to be done before any other normal import.

"/" is integer division in Python 2, so it is going to round to a whole number. If you would like a decimal returned, just change the type of one of the inputs to float:

`float(20)/15 #1.33333333`
