Comments
The add operator pops the top two objects from operand stack, adds them together, and pushes the
result back onto the operand stack. The interpreter must find two numeric objects on the top of the
stack or a typecheck error will result.
If the stack contains two integer objects, the interpreter will perform integer addition and push an
integer result onto the stack. The interpreter will perform fixed point addition and push a fixed-
point result if the stack contains a fixed-point object as either operand.
