%description
The MPFR library is a C library for multiple-precision floating-point
computations with exact rounding (also called correct rounding). It 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).

%description -l pl.UTF-8
Biblioteka MPFR to biblioteka C do obliczeń zmiennoprzecinkowych z
wielokrotną precyzją i dokładnym zaokrąglaniem (zwanym także poprawnym
zaokrąglaniem). Jest oparta na bibliotece GMP wielokrotnej precyzji.
Głównym celem MPFR jest dostarczenie biblioteki do obliczeń
zmiennoprzecinkowych wielokrotnej precyzji, która jest wydajna i ma
dobrze zdefiniowaną semantykę. Powiela dobre idee ze standardu
ANSI/IEEE-754 dla arytmetyki zmiennoprzecinkowej podwójnej precyzji (z
53-bitową mantysą).
