libmpdec
|
|
========
|
|
|
|
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 the basis for the decimal module in Python-3.3.
|
|
|
|
|
|
The library has been tested on the following platforms:
|
|
|
|
amd64: Linux, FreeBSD, OpenBSD, OpenSolaris, Windows
|
|
|
|
ppc64: AIX
|
|
|
|
x86: Linux, FreeBSD, OpenBSD, OpenSolaris, Windows
|
|
|
|
mips32: Debian
|

libmpdec++
|
|
==========
|
|
|
|
libmpdec++ is a complete implementation of the General Decimal Arithmetic
|
|
Specification. libmpdec++ is mostly a header library around libmpdec's
|
|
C functions.
|
|
|
|
The library frees users from manual memory management and has an easy API
|
|
with inline operators similar to the one in Python's decimal module. Like
|
|
Python's decimal module, libmpdec++ has a thread local context for inline
|
|
operators and other functions that use the implicit context.
|
|
|
|
In benchmarks the speed is close to libmpdec (about 4% slower due to the
|
|
copying, destructor overhead and the thread local context).
|
|
|
|
libmpdec++ has been tested on 64/32-bit Linux, 64/32-bit FreeBSD and OpenBSD
|
|
and 64/32-bit Windows.
