Floating point exception

Sometimes PSQL 6.4.2 backend reports the following:

ERROR: floating point exception! The last floating point operation either
exceeded legal ranges or was a divide by zero

even though I have no float typed attributes in any of my tables.

Do you have any idea about the problem?

Thanks
