# median

## Returns the median (middle number) of a set of
real value arguments.

**Syntax:**

median(val1, val2, ... max_val);

Argument |
Description |

val0 ... max_val |
The values to compare. |

**Returns:** Real

### Description

This function returns the median of the input values, that is,
the middle value. When the number of arguments is even, the smaller
of the two middle values is returned and the function can have as
many (real number) arguments as you require (note that more
arguments will mean that the function will be slower to parse).
This means that, for example, `median(43, 12, 25, 19, 6)`
would return 19 as it is the middle value between all the rest.

**Example:**

x = median( 0, x, room_width );

y = median( 0, y, room_height );

This will stop the player from exiting any side of the room, by
using median as a clamp. If the player, for instance, moves to the
left of the room boundary, its x will be smaller than 0. This will
mean the middle number of the first of the medians will be 0, so
the player will be jumped to (0,y).
