NumberFormat on applies when the number is output or forced to convert
to a string (for example when doing string concatenation). The variant
script below:

on mouseUp
   set the numberformat to "###.###"
   put 2.5 + 2.5 into x
   put x & cr after msg
   set the numberformat to "000.000"
   put 2.5 + 2.5 into y
   put y &cr after msg
end mouseUp

results in:

005
005.000

In the message box. Just another data point for the discussion.
