Well, use N[Ceiling[10^4 result] 10^-4] then.

P.S. Better yet, why not just use N[Round[10^4 result] 10^-4] ?

I thought that was what N[] was for so I put out N[result,4].
For some reason I still get 12 digits displayed. I looked through he help material and it says
"n must lie between $MinPrecision and $MaxPrecision. $MaxPrecision can be set to Infinity. "
I checked and these numbers are 0 and 10^6, respectively.
So, I gave up on N[] and tried Ceiling[10000*result]/10000 and damn if I didn't get "6/625"
for an answer.
I want to display a decimal result with 4 significant digits, can anyone tell me how to do it?
Thanks.
