# Colon

The colon operator has a number before and after it.

These numbers represent the (inclusive) range of the vector returned.

- Used to make vectors. This works by (from:step:to) or (from:to) with a step of 1.

` Ex: [2:4] => [2,3,4]`

` Ex: [2:.5:4] => [2,2.5,3,3.5,4]`

- Used when indexing an ENTIRE row or column of an array.

```
Ex: Array = [1,2,3; 4,5,6; 7,8,9]
Array(2,:) = [4,5,6]
```
