Is there a function in C language to calculate degrees/radians?

Question

I need to calculate an angle in C programm. Here is a method from JAVA that I need to convert to C.

private static double calculateDirection(double x, double y) {     return Math.toDegrees(Math.atan2(y, x)); } 

Is there a function like toDegrees in C language so I don't have to write all the code by myself? Thank you

Answer 1

#include <math.h>  inline double to_degrees(double radians) {     return radians * (180.0 / M_PI); }
