I normally don't work in ColdFusion but there's a FTP process at work I have to create a report for with the only option right now being a ColdFusion 8 server. This FTP feed has a few issues (trash too).
So, I make the query and then I need to convert some of the string values during the output to do some math. Before that:
How do I tell if a field in the output loop: is not blank or null, is string that can be converted into a valid number, and is not 0?
Is there a simple way of doing this w/o a lot of if statements?
Thanks!

The isNotBlank() checks that the input parameter is: not Null, not the empty string ("") not a sequence of whitespace characters (" ")
Use the strict inequality (! ==) operator to check if a variable is not null, e.g. myVar !== null . The strict inequality operator will return true if the variable is not equal to null and false otherwise.
To check if a string is null or empty in Java, use the == operator.
You can use lodash: _. isEmpty(value).
So you want to make sure that the variable is numeric but not zero?
Then you want this:
<cfif IsNumeric(MyVar) AND MyVar NEQ 0 >
