Is it a property on a DTML Document or Folder? If so, you can specify it as 
being a integer, instead of a string.

If the variable came from a form, you can add :int to the name on the form 
(filedID:int) so Zope will cast it to an integer. This will make the 
variable required, however.

You could also convert the variable to an integer on the spot, using 
_.string.atoi, like so (untested):

<!--#var "_[fieldID]" size="_.string.atoi(fieldSize)" etc="..."-->
