RE: an expression to check if a parameter is a non-zero number - comments

I want to check if the incoming parameter ImageWidth is a 
non-zero number.


test="number($ImageWidth)!=0"

this will return false if it is not a number, and false if it is zero.

I am wondering it the above expression would work?

Is there a better way to do that checking ?
