ABSTRACT The primary advantage of XS-3 coding over BCD coding is that a decimal number can be nines ’ complemented (for subtraction) as easily as a binary number can be ones ’ complemented ; just invert all bits. In addition‚ when the sum of two XS-3 digits is greater than 9‚ the carry bit of a four bit adder will be set high. This works because‚ when adding two numbers that are greater or equal to zero‚ an "excess" value of six results in the sum. Since a four bit integer can only hold values 0 to 15
