Re: 1.6!(?!)
even if 1.6! weren't uhh, what's the word? irrational? imaginary? impossible? insane?
...i'd seriously doubt they did the calculation anyways. not on a calculator at least. my ti89 (otherwise known as "proof god exists") craps itself trying to do a factorial of a five digit number.
it takes maple to crank out this enormous number. anyone else here have maple or a similar program? i considered posting 41471!, but, well, it'd severly piss off everyone trying to READ this thread. instead, i'll just post a screenshot.
you'll have to take my word for it that there's 32 and half more screens where that came from.
edit: checking the (incorrect) calculation in maple, btw, it does render the same answer. maple uses, probably, the same algorithm that will allow it to (incorrectly) render factorials of decimals.
at first, i thought even that bit of calculation was wrong, but i missed a pair of parenthesis. because the op did and i copied that.
order of operations, kids.

W := 0.1710661910*108
> W:=(41469.4 + 1.6)! / (41469.4)!*(1.6)!;
W := 0.3496295939*108
