Static Methods

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