Ruby - Why is output 2 and not 3?

Question

x = 0
y = 1
puts x == y ? y : (x ? 2 : 3)

I expect: x is different from y, so instead of putting out y, expression in parentheses is evaluated; since x is 0, 3 should be outputted. Why is 2 instead?

Answer 1

In ruby zero value is not false like c++ for example.
