> By the way, is there a perl module to do calculations with money? We use Math::BigInt to do fixed point. We couldn't get the other math modules to work a few years back. Our wrapper (Bivio::Type::Number) normalizes the rounding and allows subclasses to specify precision, decimals, min, max, etc. It's not fast, but fast enough. :-) It's part of bOP, which is available under the Artistic license from http://www.bivio.biz/hm/download-bOP
We don't do too much math in the database, i.e. with PL/SQL and such. One thing we have done which has really helped is to define the sign of all amounts/quantities so that we can use SQL's SUM() function. Our database is normalized, which speeds development and reduces bugs. Using SUM() keeps queries fast (<100MS) even processing ~1K rows to produce a portfolio. Cheers, Rob
