[xml] xpath's number function

["Agustin Villena" <avillena tutopia com>]

Hi
      We have a doubt about the xpath's number() function: If we process a 
ten digits number, the function outputs it in exponential format.
   Is this limit the w3c standard? Is there any standard function (like 
"number") that processes large numbers without the exponential formatting 
issue?

Thanks
