Ahhh... It sounds like you're coming from an older version of Mathematica. I too had this problem when I switched to 4.0. It appears that the definition of the N function has changed since then. What you now need to use is the NumberForm function (section 2.8.7). It seems to operate in a fashion similar to the old N. Regards, J.
