public static int round(float d)
Math.round(float). This merely rounds its
 argument to the nearest int, where x.5 rounds up to x+1. Semantics of this shortcut
 differ slightly from Math.round(float) in that half rounds down for negative
 values. -2.5 rounds to -3, not -2. For purposes here it makes no difference.d - real value to roundintpublic static float distance(float aX,
