degrees-radians.h
// Converts degrees to radians.
#define degreesToRadians(angleDegrees) (angleDegrees * M_PI / 180.0)
// Converts radians to degrees.
#define radiansToDegrees(angleRadians) (angleRadians * 180.0 / M_PI)

Will be problem if use like that:
degreesToRadians(10+5)

Suppose change to (with additional brackets):

#define degreesToRadians(angleDegrees) ((angleDegrees) * M_PI / 180.0)
#define radiansToDegrees(angleRadians) ((angleRadians) * 180.0 / M_PI)
