Point_2 FSRTraits_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()) <= 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.
