Negative return on degrees to radians function

[darth...@googlemail.com]

When you enter an angle of greater than 180 deg you get a negative return value, this is incorrect.

The formula for the function is radians = degrees * PI /180. Where does a negative return fit in.

Thanks for the comment.   I thought about making this change, but decided to leave things as they are.

Degrees->radians returns an angle in the range -Pi to Pi, and radians->degrees returns an angle in the range 0 to 360.
