Method

floatdistance(float x1, float y1, float x2, float y2)
2D distance formula. 
double xdiff = x2 - x1;
double ydiff = y2 - y1;
return (float) Math.sqrt((xdiff * xdiff + ydiff * ydiff));
floatdistance(float x1, float y1, float x2, float y2)
Returns the distance between two points. 
float v1 = Math.abs(x1 - x2);
float v2 = Math.abs(y1 - y2);
return (float) Math.sqrt((v1 * v1) + (v2 * v2));
floatdistance(float x1, float y1, float x2, float y2)
distance 
return (float) Math.sqrt((float) Math.pow((x2 - x1), 2.0) + (float) Math.pow((y2 - y1), 2.0));
floatdistance(float[] p1, float[] p2)
distance 
return (float) Math.sqrt(squareDistance(p1, p2));
doubledistance(float[] values1, float[] values2)
distance 
if (values1 != null && values2 != null) {
    if (values1.length == values2.length) {
        float sum = 0;
        for (int i = 0; i < values1.length; i++) {
            sum += (values2[i] - values1[i]) * (values2[i] - values1[i]);
        return Math.sqrt(sum);
return -1;
doubledistance(int ax, int ay, int bx, int by)
distance 
int length_A = 0;
int length_B = 0;
if (bx > ax) {
    length_A = bx - ax;
} else {
    length_A = ax - bx;
if (by > ay) {
...
intdistance(int first, int second)
distance 
return NumberOfSetBits(first ^ second);
doubledistance(int fx, int fy, int sx, int sy)
distance 
final int dx = sx - fx;
final int dy = sy - fy;
return Math.sqrt(dx * dx + dy * dy);
Stringdistance(int one, int two)
distance 
if (one > two) {
    return (one - two) + "px below";
} else {
    return (two - one) + "px above";
doubledistance(int px, int py, int x1, int y1, int x2, int y2)
Calculates the distance between a point and a line segment. 
double length2 = distance2(x1, y1, x2, y2);
if (length2 == 0) {
    return Math.sqrt(distance2(px, py, x1, y1));
double r = ((px - x1) * (x2 - x1) + (py - y1) * (y2 - y1)) / length2;
if (r <= 0.0) {
    return Math.sqrt(distance2(px, py, x1, y1));
if (r >= 1.0) {
    return Math.sqrt(distance2(px, py, x2, y2));
int x = (int) (x1 + r * (x2 - x1));
int y = (int) (y1 + r * (y2 - y1));
return Math.sqrt(distance2(px, py, x, y));
