Vision System FH/FZ5 series Hardware Setup Manual (Z366)
2's complement Binary numbers are generally used to represent negative numbers.
Negative numbers are expressed by "Inverting all bits of a positive number and
adding 1 to the result".
(Example) "í1" is expressed as 2's complement
"í1" can be calculated by "0-1".
There are methods for simple calculation without performing this kind of computa-
tion.
For instance, "Negative number = inverting all bits of a positive number and then
adding 1 to the result".
The first digit is used to judge whether the number is positive or negative.
When 0: Positive number (or 0)
When 1: Negative number
The advantage of two's complement numbers is that positive and negative num-
bers can be used as is in calculations.
(Example) When í1+10=9
