The Dec package is a work-in-progress, starting from a Julia wrapper around the decNumber C library, which provides a software implementation of the packed decimal formats of the IEEE 754-2008 Decimal Floating-Point Arithmetic specification.
32-bit, 64-bit, and 128-bit decimal floating-point types dec32, dec64, and dec128, respectively, are provided.
I hope to also have the arbitrary precision support provided later,
once I have finished with the IEEE packed decimal formats.
Note: this is meant to also be used with @stevengj's excellent DecFP.jl package, which provides support for the 3 IEEE binary decimal formats.
The Dec package currently requires the Julia 0.4 release.
dec64 and the other types mentioned above can be constructed from strings by parse(dec64, "123.45") or dec64"123.45", the same thing goes for dec32 and dec128.
Currently, only a few of the simple functions are supported, any help fleshing this out would of course be appreciated, as well as comments on how to improve the Julia code.
I currently am figuring out how to use BinDeps, and have only been testing on 64-bit Mac OS X so far.
