CGAL users discussion list

[Ben Supnik <>]

Hi Y'all,

The docs for make_conforming_Delaunay_2 say that it requires 
ConformingDelaunayTriangulationTraits_2. traits.

ConformingDelaunayTriangulationTraits_2 is labeled as having "Any model 
of Kernel concept. In particular, all CGAL kernels."

But...this doesn't seem correct to me - am I right in thinking that some 
CGAL exact pred exact construction kernels do not have sqrt?  The one I 
was using did not, and I get a compile failure due to being unable to 
tkae the sqrt of a number.

If sqrt is indeed required and not in all kernels, is there a way to get 
an exact predicate/exact construction kernel without one of LEDA or GMP?

cheers
ben
