# random

## Returns a random real number between 0 and
n.

**Syntax:**

random(n);

Argument |
Description |

n |
The upper range from which the random number will be
selected. |

**Returns:** Real

### Description

This function is good for probabilities where returning an
integer (whole number) is not necessary. For example,
`random(100)` will return a value from 0 to 99, but that
value can be 22.56473! You can also use real numbers and not
integers in this function like this - `random(0.5)`, which
will return a value between 0 and 0.4999999.

**NOTE:** This function will return the same value every time
the game is run afresh due to the fact that GameMaker: Studio
generates the same initial random seed every time to make debugging
code a far easier task. To avoid this behaviour use `randomize` at the start of your
game.

**Example:**

if random(10) >= 9

{

score += 100;

}

This will produce approximately a one in ten chance of adding
100 to the score.
