##### Last updated July 17, 2001

**Version:** 1 |
**Requires:** CF5 |
**Library:** MathLib

**Description:**

Returns the coordinates of the midpoint between two points on a line on the Cartesian coordinate system.

**Return Values:**

Returns a string

**Example:**

```
<CFSET x1=1>
<CFSET y1=5>
<CFSET x2=1>
<CFSET y2=-5>
<CFOUTPUT>
Given:
<UL>
<LI>x1,y1 = (1,5)
<LI>x2,y2 = (1,-5)
</UL>
The midpoint between (#x1#,#y1#) and (#x2#,#y2#) = (#CoMidpoint(x1,y1,x2,y2)#)
</CFOUTPUT>
```

**Parameters:**

Name | Description | Required |
---|---|---|

x1 | x position of the first point | Yes |

y1 | y position of the first point | Yes |

x2 | x position of the second point | Yes |

y2 | y position of the second point | Yes |
