Get results in DEGREES when using cos, etc 1

[biot023]

Hallo.
I'm just learning affine tranformations, and am successfully rotating shapes, which is nice.
However, when I call cos or sin or tan, I only get results in radians. Does anybody know a simple method of changing this or converting the results?

Any help gratefully received.

Hello:

The transformation you need to do is simple:
The value of the angle in degrees is equal to the angle in radians multiplied by 180 and divided by PI.

Deg=rad*180.0/PI()

Maybe you can define a constant 180.0/PI() and just do the operation when you need the angle in degrees.
The way you can get the value of PI() depends on the C++ you use. In Borland C++ 4.0 it is PI() as I wrote and in the vertion for DOS it used to be M_PI.
As far as I know this is the the way to do what you want
Good luck
