If your application needs to convert angular values from radians to degrees, you can use the angtos function, which returns a string, and then convert that string into a floating point value with atof.

```(setq pt1 '(1 1) pt2 '(1 2))
```
```(setq rad (angle pt1 pt2))
```
```(setq deg (atof (angtos rad 0 2)))		 returns	90.0
```

However, a more efficient method might be to include a Radian->Degrees function in your application. The following code shows this:

```; Convert value in radians to degrees
```
```(defun Radian->Degrees (nbrOfRadians)
```
```  (* 180.0 (/ nbrOfRadians pi))
```
```)
```

After this function is defined, you can use the Radian->Degrees function throughout your application, as in

```(setq degrees (Radian->Degrees rad))	returns	90.0
```

You may also need to convert from degrees to radians. The following code shows this:

```; Convert value in degrees to radians
```
```(defun Degrees->Radians (numberOfDegrees)
```
```  (* pi (/ numberOfDegrees 180.0))
```
```) ;_ end of defun
```
