Good point. I think that the problems with using floats are well documented
(I particulary like the doc that come with IBMs java.lang.BigDecimal
package) so there shouldn't be any excuse for being surprised by how they
behave. Basically floats are fine when used for what they were desgned for,
but a liability otherwise.
Just thinking about it now, I can't remember last time I designed a database
that used float data...
