  Sample input:
Fibonacci ( 10 )
  Sample output:
55

  Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

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.
