如何在 Java 中计算两个角度测量值的差异(以度为单位),使结果在 [0°, 180°] 范围内?
How can I calculate the difference of two angle measures (given in degrees) in Java so the result is in the range [0°, 180°]?
例如:
350° to 15° = 25°
250° to 190° = 60°
/**
* Shortest distance (angular) between two angles.
* It will be in range [0, 180].
*/
public static int distance(int alpha, int beta) {
int phi = Math.abs(beta - alpha) % 360; // This is either the distance or 360 - distance
int distance = phi > 180 ? 360 - phi : phi;
return distance;
}
