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.
Prime-counting function numbers. On the other hand, the computation of formula_29 can be done using the following rules: Using his method and an IBM 701, Lehmer was able to compute formula_57. Further improvements to this method were made by Lagarias, Miller, Odlyzko, Deléglise and Rivat. Other prime-counting functions are also used because they are more convenient to work with. One is Riemann's prime-counting function, usually denoted as formula_58 or formula_59. This has jumps of 1/"n" for prime powers "p", with it taking a value halfway between the two sides at discontinuities. That added detail is used because then the function may be
