Pop two integers, floats or strings, compute whether they are equal and push the Boolean result back on the stack.

The != operator can be simulated using the Logical Not action right after the Equal (typed).

If a mix set of types is popped from the stack, conventional conversions occur. Strings may be transformed to numbers and numbers to strings as with the untyped Equal operator.
