Static Methods

arcHav(double x) double
Computes inverse haversine. Has good numerical stability around 0.
clamp(double x, double low, double high) double
Restrict x to the range low, high.
hav(double x) double
Returns haversine(angle-in-radians).
havDistance(double lat1, double lat2, double dLng) double
Returns hav() of distance from (lat1, lng1) to (lat2, lng2) on the unit sphere.
havFromSin(double x) double
inverseMercator(double y) double
Returns latitude from mercator Y.
mercator(double lat) double
Returns mercator Y corresponding to latitude.
mod(double x, double m) double
Returns the non-negative remainder of x / m.
sinFromHav(double h) double
sinSumFromHav(double x, double y) double
wrap(double n, double min, double max) double
Wraps the given value into the inclusive-exclusive interval between min and max. n The value to wrap.
