Round ( (1/(5^(1/2))) * ( Phi^N - NPhi^N ) ; 1 ) /* Figures out the result of the Nth iteration of the Fibonacci series. I had to use rounding because FM cannot resolve the irrational number Phi. Rob Poelking */ Click to copy

Figures out the result of the Nth iteration of the Fibonacci series. I had to use rounding because FM cannot resolve the irrational number Phi. This means that at very high numbers FileMaker (not the calculation) introduces error.
