Comments
The mul operator pops the top two objects from operand stack, multiplies 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 multiplication and
push an integer result onto the stack. The interpreter will perform fixed point multiplication and
push a fixed point result if the stack contains a fixed point object as either operand.
