math module for Decimals

[alex goretoy]

I've been watching this thread for couple days now. I followed the bug
report and all that stuff. It's very interesting to me how you guys talk
about this stuff. I like it alot. I a new guy to python, just fyi. I'm one
of my current projects I'm using Decimal as well and I think it be a huge
pain in the you know what that it doesn't take floats as input.

I'm currently doing this in my code:

a=str(decimal.Decimal(str(round(self.value,2)-round(float(subtract),2))))

I know it's messy and I need sleep, yawn. But you see what I'm getting at
here. I have to jump through somuch hoops to get what I wanted out of this.
To be up front, I'm not sure that's what I wanted. Too tired. Anyway, I'm
glad you guys got it pushed into 2.7 and 3.1. Thank you so much for this.

Also, another reason why I'm posting to this thread. I noticed some
error/typo in line 683 of decimal.py located on public svn repo. This is
what is looks like.

        sign = 0 if _math.copysign(1.0, f) == 1.0 else 1

I'm not trying to mention it to show someones flaws, rather I want to help
you guys. Genuinely. I want in on the action. To do what I can, or what I'm
capable of. So please do _NOT_ take it that way. This is awesome stuff,
Thank you. -A
