WebSigned and Unsigned Integers. ... If you understand how data get stored in the RAM, you may understand that all the programs on your machine run in shared memory space, ... WebZF is relevant to both signed and unsigned integers; ZF is set when all bits of the result are zero. If the integer is unsigned, CF may be tested after one of these arithmetic operations to determine whether the operation required a carry or borrow of a one-bit in the high-order position of the destination operand.
