Description
sage: n(erf(2),54) ... NotImplementedError: erf not implemented for precision higher than 53
However, MPFR contains a multiple precision implementation of erf. It should be straightforward to use.

PS: maybe this ticket is duplicate. It is not easy to search for erf
in trac, a feature, like grep -w erf
is missing,
and the TracSearch help is not very useful...

Does #1173 solve this (it uses mpmath)? It's certainly possible there to do
erf(2).n(54)
or such, not sure about your syntax as I don't have a Sage install with this patch currently. But this should do it.You are certainly correct about searching Trac. Sorry that neither this ticket nor #1173 can address that :)
