My news reader is not sure about equation above.
You probably meant ceil(pow((1+sqrt(5))/2, n)/sqrt(5))
It works well with double precision math up to nu.  After that it
would need high precision fp library, so probably [much] slower
than simple loop above at least up to n' where we run out of range
of int64 result. 

 

It seems like your newsreader don't like combinations of characters that
I considered benign. Like n=75 and n=92
