|
|
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).
