    "@dfn{GMP} (the GNU Multiple Precision Arithmetic Library) is a library for
arbitrary-precision arithmetic, operating on signed integers, rational numbers
and floating point numbers.  The precision is only limited by the available
memory.  The library is highly optimized, with a design focus on execution
speed.  It is aimed at use in, for example, cryptography and computational
algebra.")

Multiple Precision Arithmetic) and GNU@tie{}@dfn{MPFR} (Multiple Precision

The purpose of arbitrary-precision interval arithmetic is to get results that
are both guaranteed, thanks to interval computation, and accurate, thanks to
multiple-precision arithmetic.")
