Package arprec-toolkit: Information

This package supports a flexible, arbitrarily high level of numeric precision --
the equivalent of hundreds or even thousands of decimal digits (up to
approximately ten million digits if needed). Special routines are provided for
extra-high precision (above 1000 digits). The entire library is written in C++.
High-precision real, integer and complex datatypes are supported. Both C++ and
Fortran-90 translation modules modules are also provided that permit one to
convert an existing C++ or Fortran-90 program to use the library with only minor
changes to the source code. In most cases only the type statements and (in the
case of Fortran-90 programs) read/write statements need be changed. Six
implementations of PSLQ (one-, two- and three-level, regular and multi-pair) are
included, as well as three high-precision quadrature programs. New users are
encouraged to use this package, rather than MPFUN90 or MPFUN77 (see below).

This verion of the ARPREC package now includes "The Experimental Mathematician's
Toolkit". This is a complete interactive high-precision arithmetic computing
environment. One enters expressions in a Mathematica-style syntax, and the
operations are performed using the ARPREC package, with a level of precision
that can be set from 100 to 1000 decimal digit accuracy. Variables and vector
arrays can be defined and referenced. This program supports all basic arithmetic
operations, common transcendental and combinatorial functions, multi-pair PSLQ
(one-, two- or three-level versions), high-precision quadrature, i.e. numeric
integration (Gaussian, error function or tanh-sinh), and summation of series.
