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 features infrequent but serious errors with a ghc that has been compiled with the default integer-gmp. When using ghc, it is recommended to use one compiled with a modified integer-gmp, as described at

or with integer-simple, as described at

There is a hope that at some point future versions of ghc will not need any modification for hmpfr to work with them correctly.

The library includes both a pure and a mutable interface. The mutable interface should have a lot less overhead than the pure one.

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