[Dune] high precision calculation in dune

[Klaus Kaiser]

Hallo,

till now I was using a dune::FieldVector<long double, n> for representing my degrees of freedom, but I got into a calculation where I have to deal with cancellation. So I'm looking for a possibility to raise the precision of my calculation and so I want to know if it is possible to easy use a higher precision data type, something like gmp, for my FieldVector.

Greetings and thanks for a response
