Finger binary Finger binary Finger binary is a system for counting and displaying binary numbers on the fingers of one or more hands. It is possible to count from 0 to 31 (2−1) using the fingers of a single hand, or from 0 through 1023 (2−1) if both hands are used. In the binary number system, each numerical digit has two possible states (0 or 1) and each successive digit represents an increasing power of two. Note: What follows is but one of several possible schemes for assigning the values 1, 2, 4, 8, 16, etc. to fingers, not necessarily the best.
Redundant binary representation time proportional to log("n") (where "n" is the number of digit) compared to a constant-time in two's complement. It is, however, possible to "partially" convert only the least-significant portion of a redundantly represented number to non-redundant form. This allows operations such as masking off the low "k" bits can be done in log("k") time. Redundant binary representation A redundant binary representation (RBR) is a numeral system that uses more bits than needed to represent a single binary digit so that most numbers have several representations. An RBR is unlike usual binary numeral systems, including two's complement, which use a single
