# Odd and Even Check

## Odd and Even Check

(OP)
Does anyone know of a way to type an IF statement that checks if the input is odd or even?

Such as it outputs a 0 if it's even and a 1 if it's odd
Something like that?

THANKS!

### RE: Odd and Even Check

(OP)
I think I came up with a solution...

Not sure if there is an easier way, but...

test = if( (-1)^n, 1, even, odd)

If n is even it sends out a 1 if it's odd it sends out a -1.

### RE: Odd and Even Check

That says that (2^54)-1 is even, in v5. I imagine that is a precision limit.
