Method

floatdistance_to_endpoint(int x1, int y1, int x2, int y2, int x, int y)
distance_to_endpoint() - distance to closest endpoint 
return (float) Math.min(distance(x1, y1, x, y), distance(x2, y2, x, y));
floatdistance_to_endpoint(int x1, int y1, int x2, int y2, int x, int y)
Distance to closest endpoint. 
return (float) Math.min(distance(x1, y1, x, y), distance(x2, y2, x, y));
doubledistance_to_line(double x1, double y1, double x2, double y2, double x3, double y3)
Computes the distance from a point to a line segment. 
double x12 = x2 - x1;
double y12 = y2 - y1;
double x13 = x3 - x1;
double y13 = y3 - y1;
double D12 = Math.sqrt(x12 * x12 + y12 * y12);
double pp = (x12 * x13 + y12 * y13) / D12;
if (pp < 0.0) {
    return (float) Math.sqrt(x13 * x13 + y13 * y13);
...
intdistanceAbs(final int a, final int b)
distance Abs 
return a > b ? a - b : b - a;
doubledistanceBase(double[] coord1, double[] coord2, int order)
Calculates the distance between two coordinates. 
if (coord1.length != coord2.length)
    throw new IllegalArgumentException("Number of dimensions is not equal");

double distance = 0;
for (int d = 0; d < NUM_DIMENSIONS; d++) {
