The package comes in two versions: one completely self-contained, all-Fortran version that is simple to install and one version based on the MPFR package that is more complicated to install but runs somewhat faster on most applications. All basic arithmetic operations and transcendental functions are supported, together with several special functions. This package permits one to perform floating-point computations (real and complex) to arbitrarily high numeric precision, by making only relatively minor changes to existing Fortran-90 programs (mostly changes to type statements). 60 digits) for Fortran and C++ (new users should try DDFUN or DQFUN).
