arbitrary precision real (mpfr) or complex (mpc) numbers, without control
on the rounding. For the time being, only the few functions needed to
implement the floating point approach to complex multiplication are
implemented. On the other hand, these comprise asymptotically fast
multiplication routines such as Toom–Cook and the FFT. ")

"PARI/GP is a widely used computer algebra system designed for fast
computations in number theory (factorisations, algebraic number theory,
elliptic curves...), but it also contains a large number of other useful

polynomials, power series, algebraic numbers, etc., and a lot of
transcendental functions.
PARI is also available as a C library to allow for faster computations.")

(description
"bc is an arbitrary precision numeric processing language. Syntax
is similar to C, but differs in many substantial areas. It supports
interactive execution of statements. bc is a utility included in the
POSIX P1003.2/D11 draft standard.
Since the POSIX document does not specify how bc must be implemented,
this version does not use the historical method of having bc be a
compiler for the dc calculator. This version has a single executable
that both compiles the language and runs the resulting `byte code'. The
byte code is not the dc language.")
