Moderator note: author requested topic lock.

Outputs the nth square number:

Code:

1   => 4
2   => 9
3   => 16
; ...
100 => 10000
101 => 10201
102 => 10609

Code:

Square(n) {
   Return n = 1 ? 4 : Square(n-1)+(3+(n-1)*2)
}

Seems to want to crash with any number higher than 287 on my comp.

n=0 should be retrieved -> 0^2 = 0

I don't think this is useful..

That doesn't look right. Have you tried sq := n ** 2
