In IBM computers of the 704, 709, 7090, 7094 line, the numbers were in sign-magnitude form, different from the two's complement form in common use today. So there were both Positive zero ane Negative zero on the machine, and there were different test instructions depending on what you wanted to do TZE Transfer (jump, branch) on zero TNZ Transfer on no zero TPL Transfer on plus TMI Transfer on minus CAS compares two numbers and takes the next instruction if smaller, the instruction after that if equal, and the one after that if larger. Positive zero was considered greater than negative zero for this instruction. -- .~.
