|
|
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.
