Hi , all
I have been out some time , but seeing your post , i have to say that i have
a similar problem. Much worse , as i have to deal with 2 , 3,4,5 and 6
decimal places for various kinds of quantities (stocks, financial , currency
conversions ..) so the solution i used to be in the safe side (I mean , i
have ib 5.6 and fb 1.0 installations and cannot make a substitution by
contract) and not be nagged by diferent dialects , I implemented a UDF to
force roundings , use a datatype of 7 decimal points and in the triggers , i
check for attempts to store a 7th decimal that is not 0 , throwing a
database error in that case. I'm eager to know different approaches to this
problem.

Hope
