Bit operator in expression language

Ignition

You're using Bitwise AND where you should be using Logical AND.

if(47 & 64, true, false) returns false.
if(48 & 64, true, false) returns false.
if(47 && 64, true, false) returns true.
if(47 && 64, true, false) returns true.
if(0 && 64, true, false) returns false.

So, you don't need the > 0 and since you are returning a bool you don't need the if(). You can replace the whole lot with the expression,
i && 64
