| Description: | ARPREC is a software package for performing arbitrary precision
arithmetic. It consists of a revision and extension of Bailey's
earlier MPFUN package, enhanced with special IEEE numerical
techniques. Features include:
* Written in C++ for broad portability and fast execution.
* Includes C++ and Fortran 90/95 interfaces based on custom data-types
and operator/function overloading, which permit the library to be
used with only minor modifications for many conventional C++ and
Fortran-90 programs.
* Includes all of the usual arithmetic operations, as well as many
transcendental functions, including cos, sin, tan, arccos, arcsin,
arctan, exp, log, log10, erf, gamma and Bessel functions.
* Supports three arbitrary precision data-types: mp_real, mp_int
and mp_complex.
* Supports many mixed-mode operations between arbitrary precision
variables or constants and conventional variables or constants.
* Includes special library routines, incorporating advanced
algorithms for extra-high precision (above 1000 digits) computation.
* Includes a number of sample application programs, including programs
for quadrature (numerical definite integrals), PLSQ (integer relation
finding) and polynomial root finding.
* Includes the "Experimental Mathematician's Toolkit". This is a
self-contained interactive program that performs many operations
typical of modern experimental mathematics, including arithmetic
expressions, common transcendental functions, infinite series
evaluation, definite integrals, polynomial roots, user-defined
functions, all evaluated to a user-defined level of numeric
precision, up to 1000 decimal digits. |
