# Numbers in PythonΒΆ

Get your computer to the Python shell (see *Setup Your Environment* if you need help)

In Computers we have different types of Numbers, we have whole numbers (Integers), like 5, decimal numbers like $53.26 and Floating point numbers like 3.1415926.....

Integers (whole numbers):

```
>>> 5
>>> 10
>>> 9999
```

Floating point numbers (numbers with decimals):

```
>>> 1.0
>>> .00000567
>>> 3.14159
```

- We can do math on numbers with “Arithmetic Operators”:
- addition: +
- subtraction: -
- multiplication: *
- division: /

Try doing some math in the interactive shell:

```
>>> 2 + 2
>>> 10 - 5
>>> 400 * 12
>>> 10 / 3
```

- You can Compare numbers using “comparison operators”:
- == Equal to
- != Not equal to
- < Less than
- > Greater than
- <= Less than or equal to
- >= Greater than or equal to

```
>>> 5 == 5
>>> 5 >= 6
>>> 16 * 2 == 32
```

Decimal numbers are handled in the `decimal`

module in python, and are not directly covered in this introduction.
