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