Hi Scott,
Google math is great. It will even evaluate factorials up to about 170. 170! =
7.257416e+306
Most calculators show an overflow beyond 60!
But Wolfram alpha will evaluate 300! =
3.0605751221644063603537046129726862938858880417 × 10^614
And God knows how much further.
Live code doesn't have a factorial function.
I wrote one that works up to 170! It uses the traditional iterative method
below 60! and the Sterling approx beyond that. Beyond 170! LC shows an
overflow:
function fact n
if n < 60 then
return factorial (n)
else
put exp(1) into e
return ((n/e)^n) * (sqrt(2*pi*n)) --This is the Sterling approx.
end if
end fact
function Factorial n
if n = 1 then
return 1
else
return n * factorial(n-1)
end if
end factorial
