Dear All,
I have recently written some code for fixed point arithmetic which I would be happy to contribute to Boost, if it is considered worthy.
I'm interested. You may not know that there was a fixed decimal proposal that rejected...5 years ago now?

You'll probably want to try and look at the review comments and see why it was rejected.
I'll try to find the review but a cursory glance looks like this is supposed to be for something like BCD ala http://en.wikipedia.org/wiki/Binary-coded_decimal What I'm referring to is binary scaling ala http://en.wikipedia.org/wiki/Binary_scaling Maybe there is too much confusion using the term fixed-point? Although fixed is such a nice class name to use for a drop in replacement for float on machines that have a FPU... I can't really think of anything I'd accept in its place. Maybe boost::binary_scaling::fixed and boost::binary_decimal::fixed could coexist?

AFAIK Boost.Integer doesn't support 64-bit types which forced me to roll my own solution.
That's incorrect. There is support for 64-bit types. The documentation, unfortunately, doesn't say so -- you have to read the header. I use boost::int64_t and boost::uint64_t in date-time -- works on every platform boost is ported to AFAIK.
Oh? Okay I'll take a look again Thanks, Michael Marcin
