Not with value() there isn't. I've written a convert-to-number routine tha 
does tell you this info. I can mail it if you like.

  sequence x
  if integer(SOMEVAL) then
	x = sprintf("%d", SOMEVAL)
  else
      x = sprintf("%15.15f",SOMEVAL)
      -- Remove trailing zeros.
      for i = length(x) to 1 by -1 do
       if x[i] != '0' then
         exit
       end if
       x = x[1..i-1]
      end for
  end if
