You can assign the float pi =3.141592653589793. The establish the conversion ratio float cr = pi/180.0, which provides the conversion of degrees to radians. Presume you have a float variable defined as float ang = 60.0, which is expressed in degrees. Then float angr = cr * ang, results in the conversion of the angle from being expressed in degrees to being expressed in radians. Kocmotex
