aern2-mp: Multi-precision floats via MPFR

[ bsd3, library, math ] [ Propose Tags ]

Arbitrary-precision dyadic numbers and interval arithmetic, via the types:

By default, using hmpfr when compiling with ghc >=7.10. Older versions of ghc are no longer tested.

Set flag MPFRRounded to bind MPFR not via hmpfr but via a tweaked version of package rounded:

This backend is considerably faster than hmpfr. It is likely to become the default in future.

There is a plan to add an Integer-only backend so that this library can be used without MPFR.

Use a MPFR backend (default); Integer backend is planned


Use rounded (Numeric.RoundedSimple) as MPFR backend (not default)


Use -f <flag> to enable a flag, or -f -<flag> to disable that flag. More info
