的#include＆LT;＆math.h中GT;内嵌双to_degrees（双弧度）{
    返回弧度*（180.0 / M_PI）;
}
 

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

#include <math.h>

inline double to_degrees(double radians) {
    return radians * (180.0 / M_PI);
}
