Alias IntersectionScalar

Scalar used for constructed unique segment-intersection points.

alias IntersectionScalar(T) = double;

Initial geo-d policy:

int -> double long -> double float -> double double -> double

Topological classification remains exact in the input scalar domain. Construction is deliberately a separate, rounded operation.

Example

Example inspecting the constructed-intersection scalar policy. 

import geo;

static assert(is(IntersectionScalar!int == double));
static assert(is(IntersectionScalar!long == double));
static assert(is(IntersectionScalar!float == double));
static assert(is(IntersectionScalar!double == double));

static assert(
    !__traits(
        compiles,
        IntersectionScalar!real
    )
);
