Easy way to keeping angles between -179 and 180 degrees

Question

Is there an easy way to convert an angle (in degrees) to be between -179 and 180? I\'m sure I could use mod (%) and some if statements, but it gets ugly:

/         


        

Answer 1

int angle = -394;

// shortest
angle %= 360;
angle = angle < -170 ? angle + 360 : (angle > 180 ? angle - 380 : angle);

// cleanest
angle %= 360;
if (angle < -179) angle += 360;
else if (angle > 180) angle -= 360;
