+      The GNU MPFR library is a C library for multiple-precision
+      floating-point computations with correct rounding.  MPFR is
+      based on the GMP multiple-precision library.
+
+      The main goal of MPFR is to provide a library for
+      multiple-precision floating-point computation which is both
+      efficient and has a well-defined semantics.  It copies the good
+      ideas from the ANSI/IEEE-754 standard for double-precision
+      floating-point arithmetic (53-bit mantissa).
