distance

NAME

distance() - the Euclidean distance between two points

SYNOPSIS

float distance(int * | float * point_a, int * | float * point_b)

DESCRIPTION

Returns the Euclidean distance between the points 'point_a' and 'point_b':
the square root of the sum of the squares of the differences of their
corresponding coordinates. The result is always a float.

Both points must have the same dimension (array size); otherwise a runtime
error is raised ("distance: cannot take the distance of vectors of
different sizes."). Each coordinate may independently be an int or a float;
a coordinate of any other type raises a runtime error.

EXAMPLE

distance(({ 0, 0 }), ({ 3, 4 }));       // 5.0
distance(({ 1.0, 1.0 }), ({ 4.0, 5.0 })); // 5.0
