 Software implementation of the IEEE 754-2008 Decimal Floating-Point
 Arithmetic specification, aimed at financial applications, especially
 in cases where legal requirements make it necessary to use decimal, and
 not binary floating-point arithmetic (as computation performed with
 binary floating-point operations may introduce small, but unacceptable
 errors).
