Hello, I have a tag as such: <dtml-var DMT_S_E null=N/A> DMT_S_E is a variable that comes from a SQL Method with a PostgreSQL backend. DMT_S_E is of pgsql data-type "float8". Yet, for some reason, when I do <dtml-var "_.int(DMT_S_E)" null=N/A>, I get an error about not being able to convert it to int. This is where the value is null, and therefore "N/A" gets displayed. So, does this mean that the "null" value has to be of the same data-type as the variable itself? If so, this isn't documented in the DTML Reference. I don't want to use "0" (Zero) as this would not be accurate. Is there an easy alternative, or am I going to have to use an if-then statement?
