Hello, If you are working on finance type stuff, you may be interested in my Decimal library: http://article.gmane.org/gmane.comp.lang.haskell.cafe/8734 I think my 'last even' rounding algorithm is broken because I misread the spec -- so be warned: hunk ./Decimal/Operations.hs 78 - | roundHint == RoundOneHalf && (lastIsEven d) = (Decimal s (coef + 1) exp) + | roundHint == RoundOneHalf && (lastIsEven d) = (Decimal s (coef + 1) exp) -- FIXME: this may be wrong, see pep327 Jeremy Shaw At Fri, 10 Feb 2006 14:09:23 -0500, Rob Tougher wrote:

I'm currently working on a mathematics library in Haskell. I'm not a mathematician -- I'm basically writing this library as an excuse to learn mathematics and Haskell at the same time.

Feel free to check out the code:

My main focus is financial mathematics (options pricing, etc), but I took a detour last week and implemented basic matrix stuff. I might work on some Linear Programming algorithms (simplex, interior point) before returning to finance.
