euclideanDistance
fn
CommonType!(ElementType!(Range1), ElementType!(Range2)) euclideanDistance(Range1, Range2)(Range1 a, Range2 b) if (isInputRange!(Range1) && isInputRange!(Range2))Computes Euclidean distance between input ranges a and b. The two ranges must have the same length. The three-parameter version stops computation as soon as the distance is greater than or equal to limit (this is useful to save computation if a small distance is sought).
