const HxVec2Double HxVec2Double::SMALL_VAL = HxVec2Double(0, 0) [static]
 

A small value w.r.t to the comparison operators "<" and ">".

Not actually the minimum to avoid overflow.

const HxVec2Double HxVec2Double::LARGE_VAL = HxVec2Double(1e300, 1e300) [static]
 

A large value w.r.t to the comparison operators "<" and ">".

Not actually the maximum to avoid overflow.
