Yes, that would work, but it's not what I need: I retrieve a table column value via a DB query and store it in an AVP. Such column can store NULL, 0, 1, 2 ... 8. How can I check if the AVP has an integer value (including 0)?: 1) In case I retrieve 1...8 from the database: - if $avp(column) => true - if $avp(column) >=0 => true 2) In case I retrieve 0 or NULL from the database: - if $avp(column) => false - if $avp(column) >=0 => ERROR (invalid comparison) So there is no way to determine if the retrieved value is *any* integer (including 0), is there? PS: I *strongly* hate the fact that 0 is threated as "false" or "non true", why?
