In order to convert radians to degrees, PHP provides the rad2deg function whereas Python’s NumPy library provides np.rad2deg.
In C++ there is no standard function to convert radians to degrees.
However, you can use this simple snippet:
#define _USE_MATH_DEFINES #include <cmath> /** * Convert the angle given in radians to degrees. */ template<typename F> F rad2deg(F angle) { return angle * 180.0 / M_PI; }
This will work for double
, float
etc. and returns the angle in degrees.
The formula is pretty simple:
\text{Degrees} = \frac{\text{Radians} \cdot 180°}{\pi}
