The hmpfr package

[Tags:bsd3, library]

Haskell binding to the MPFR library. This version is compatible with MPFR 2.4.* and later and will not work with previous releases of the MPFR library.

Since MPFR uses GMP, this library does not work correctly with a ghc that has been compiled with integer-gmp. When using ghc, this library will require that the ghc is compiled with integer-simple.

The library includes a mutable interface in addition to the pure one. These functions should have a lot less overhead than the pure ones.

Some simple examples of usage can be found in demo/Demo.hs.
