Image Binarylogarithm plot.png thumbnail right 200px Plot of log sub 2 sub n In mathematics , the binarylogarithm log sub 2 sub   n is the logarithm to the Binary numeral system base 2 . It is the inverse function of n     2 sup n sup . The binarylogarithm of n is the power to which the number 2 must be raised to obtain the value  n . This makes the binarylogarithm useful for anything involving powers of 2 , i.e. doubling. For example, the binarylogarithm of 1 is 0, the binarylogarithm of 2 is 1, the binarylogarithm of 4 is  2, the binarylogarithm of 8 is 3, the binarylogarithm of 16 is 4 and the binarylogarithm of 32 is  5.

For the theorem in probability theory Law of the iterated logarithm In computer science , the iterated logarithm of n , written log star   n usually read log star , is the number of times the logarithm function must be iteratively applied before the result is less than or equal to 1. The simplest formal definition is the result of this recursive function math log n begin cases 0 & mbox if n le 1 1 log log n & mbox if n 1 end cases math On the positive real numbers, the continuous super logarithm inverse tetration is essentially equivalent math log n lceil text slog e n rceil math but on the negative real numbers, log star is 0, whereas math lceil text slog e x rceil 1 math for positive x , so the two functions differ for negative arguments. Image Iterated logarithm.png right 300px thumb Figure 1. Demonstrating lg 4 2 In computer science, lg star is often used to indicate the binary iterated logarithm, which iterates the binarylogarithm instead. The iterated logarithm accepts any positive real number and yields an integer . Graphically, it can be understood as the number of zig zags needed in Figure 1 to reach the interval 0, 1 on the x axis. Mathematically, the iterated logarithm is well defined not only for base 2 and base e , but for any base greater than math e 1 e approx1.444667 math .

A binary protocol is a network protocol protocol which is intended or expected to be read by a machine rather than a human being, as opposed to a plain text protocol such as IRC , SMTP , or HTTP . Binary protocols have the advantage of terseness, which translates into speed of transmission and interpretation. There has always been tension between two software development camps that believe new protocols should preferably be text based or binary, respectively. In recent years, with the ready availability of network bandwidth and mass storage, the text based camp has been gaining significant ground XML based systems are nearly ubiquitous but the debate continues ref http www.webservices.org weblog mark little soap for the masses A representative discussion of text and binary protocol debate, by Mark Little ref .

A binary clock is usually a clock which displays traditional sexagesimal time in a binary numeral system binary format. Originally, it showed each decimal digit of sexagesimal time as a binary value, but presently binary clocks also exist which display hours, minutes, and seconds as binary numbers. Most binary clocks are digital , although analog signal analog varieties exist. True binary clocks also exist, which indicate the time by successively halving the day. Thus these clocks do not use hours, minutes, or seconds. Similar clocks, based on Gray code d binary, also exist.

ISBN 1 85233 751 6. ref Contact binaries are sometimes confused with common envelope s. However, whereas the first refers to a stable configuration of two touching stars in a binary with a typical lifetime of millions to billions of years, the latter describes a dynamically unstable phase in binary evolution which either expels the stellar envelope or merges the binary in a timescale of months to years.
