# FunctionName

## Syntax

`int quickMedian(int low, int high)`

## Arguments

**low:**
- lowest put/get cell that contains values, usually zero.

**high:**
- highest put/get cell that contains values, usually calculated as (radius*2+1) * (radius*2+1)

## Return

- The return value is the median value.

## Description

- specify.

## Example

%ffp
ctl(7): "Radius ", range=(1,15), val=1, page=1
ForEveryTile:
{
for (y=y_start; y<y_end; y++)
for (x=x_start; x<x_end; x++)
for (z=0; z<3; z++)
{
quickFill(x,y,z,0,ctl(7),0,0,X,Y);
pset(x,y,z,quickMedian(0,(ctl(7)*2+1)*(ctl(7)*2+1)-1));
}
return true;
}

## Comments

- Please notice that quickMedian() works fast for radius values from 1 to 8, but above that it gets very slow. There are much faster algorithms that use tables or histogram for calculating median values with a high radius. There are also slightly faster algorithms for medians with a radius of 1 or 2.
