# degtorad

## Converts the given degrees to radians.

**Syntax:**

degtorad(deg);

Argument |
Description |

deg |
The degrees to convert. |

**Returns:** Real

### Description

In GM all the trigonometric functions work in radians, but most
people work in degrees and this means that to convert your degrees
into radians you need to use this function. For example,
`degtorad(180)` returns 3.14159265 radians. This function
translates degrees into radians using the formula:

angle_radians = angle_degrees * pi / 180

**Example:**

val = degtorad(90);

This will set val to pi/2.
