Point_2 VSSRTraits_2::ConstructRoundedPoint_2::operator()

(

Point_2

p

)

Given a point, constructs a point whose coordinates are rounded.

Warning

To guarantee a valid result, the order of the coordinates of two points p and q must be preserved: \(p.x() < q.x()\) implies \(rounded(p.x()) \leq rounded(q.x()) \) (and similarly for the y coordinate).

Note

If Evaluation_tag is true, the algorithms sort the vertices and call Evaluate when two vertices are likely to not respect this condition.
