+MPFI is a library for interval arithmetic, which is built upon the MPFR
+multiple precision floating-point arithmetic.
+
+MPFI is intended to be a portable library written in C for arbitrary
+precision interval arithmetic with intervals represented using MPFR
+reliable floating-point numbers. It is based on the GNU MP library and
+on the MPFR library.  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 rounding provided, for each
+operation or function, by MPFR.  Further advantages of using MPFR are
+its portability and compliance with the IEEE 754 standard for
+floating-point arithmetic.
