39 libmpdec is a fast C/C++ library for correctly-rounded arbitrary
40 precision decimal floating point arithmetic. It is a complete
41 implementation of Mike Cowlishaw/IBM's General Decimal Arithmetic
42 Specification. The full specification is available here:
43
44 http://speleotrove.com/decimal/
45
46 libmpdec will - with minor restrictions - also conform to the IEEE
47 754-2008 Standard for Floating-Point Arithmetic, provided that the
48 appropriate context parameters are set.
49
50 libmpdec++ is a complete implementation of the General Decimal Arithmetic
51 Specification. libmpdec++ is mostly a header library around libmpdec's C
52 functions.
