libmpfi-dev - 1.5.3+ds-5 main

This package provides a C library of functions for interval arithmetic
computations with arbitrary precision.
.
The basic principle of interval arithmetic consists in enclosing every number
by an interval containing it and being representable by machine numbers: for
instance it can be stored as its lower and upper endpoints and these bounds
are machine numbers, or as a centre and a radius which are machine numbers.
.
The arithmetic operations are extended for interval operands in such a way
that the exact result of the operation belongs to the computed interval.
.
The purpose of an arbitrary precision interval arithmetic is on the one hand
to get guaranteed results, thanks to interval computation, and on the other
hand to obtain accurate results, thanks to multiple precision arithmetic. The
MPFI library is built upon MPFR in order to benefit from the correct roundings
provided by MPFR. Further advantages of using MPFR are its portability and
compliance with the IEEE 754 standard for floating-point arithmetic.
.
This package provides the static library and symbolic links needed for
development.
