[Dune-devel] [dune-fem] Arbitrary precision arithmetic

[Oliver Sander]

Hi,

the file

  dune-geometry/dune/geometry/quadraturerules/tensorproductquadrature.hh

constructs simplex quadrature rules by multiplying 1d rules.  It is not
as intelligent as it could be, and creates too many points, but it does
work.

Best,
Oliver
