(bī’ n∂ rē) Composed of only two elements. A number system in which only two digits, 0 and 1, are used, the position of the digits representing powers of two; e.g., 11011 represents 2^{4}+2^{3}+2^{1}+2^{0}=16+8+2+1 or the decimal number 27. See Figure N-4. Negative numbers may be represented by a minus sign or by codes such as the one’s-complement or two’s complement codes.
