Fuck I thought that was an absolute factorial.
Aren’t all factorials absolute factorials?
Introducing, the signed factorial: ¡n! = n × -(n-1) × (n-2) x -(n-3) x … x (-1)^(n-2)(2) ×(-1)^(n-1)(1)
We did it Lemmy!
Where’s our Nobel prize.
There’s no Nobel price for mathematics, but I can accept the one for peace instead.
I’d prefer an alternative definition that starts with the base case ¡0! = 1, and then for n > 0 we define ¡n! = n * ¡(n-1)!
How are you going to flip the signs though?
It’s the same calculation but you also take a shot of vodka for all integers less than n but greater than 0
