The definition of numeric calculation was changed between dialect 1 and 3 with Interbase 6. This is described in the Interbase 6 getting started (available from the website). Basically in dialect 1 this type of division overflowed into double precision, it doesn't in dialect 3 and your result doesn't fit and it raises an arithmetic overflow.

The following SQL failed in the new database (fb 2.5 dialect 3). It worked in fb 1.5 (dialect 1). ---->>>> Even if i try to cast the result in a numeric value. ---> That's what i do not understand.I can understand that a numeric divided by another numeric can give a float... but why the cast does'nt work ? SELECT cast( cast(8975.00038147 as numeric(18,8)) / cast(1.06 as numeric(18,8)) as numeric(18,8))FROM RDB$DATABASE notes : - the values 8975.0038147 come from is a field value. field definition is float.- the problem that i actually have occured in a procedure where there is a computed variable.CA_BRUT_HT = :CA_BRUT_TTC_fact / :TAUX_TVA; where the three variables are defined as numeric (18,8).But ibexpert show me the SQL that give the problem (the select i pasted in this mail). What's the best to do ? working with float variables ? Thanks in advance for the light you can give me with that problem. Best regards,Marianne
