How to implement parity check in If snippet?

Question

MODX

I'm trying to make a different output depending on whether idx is even or not.
In the chunk I use the If snippet

[[!If?
    &subject=`[[+idx]] % 2`
    &operator=`EQ`
    &operand=`0`
    &then=`Это чётное`
    &else=`Это не чётное`
]]

However, regardless of idx, odd is output.

Answer 1

Это чётное
