41Virtual method table — A virtual method table, virtual function table, dispatch table, or vtable, is a mechanism used in programming language to support dynamic dispatch (or run time method binding).Suppose a program contains several classes in an inheritance hierarchy …
42Prime-counting function — In mathematics, the prime counting function is the function counting the number of prime numbers less than or equal to some real number x cite book |first=Eric |last=Bach |coauthors=Shallit, Jeffrey |year=1996 |title=Algorithmic Number Theory… …
43Branch table — In computer programming, a branch table (sometimes known as a jump table) is a term used to describe an efficient method of transferring program control (branching) to another part of a program (or a different program that may have been… …
44Gamma function — For the gamma function of ordinals, see Veblen function. The gamma function along part of the real axis In mathematics, the gamma function (represented by the capital Greek letter Γ) is an extension of the factorial function, with its… …
45Decision table — Decision tables are a precise yet compact way to model complicated logic.[1] Decision tables, like flowcharts and if then else and switch case statements, associate conditions with actions to perform, but in many cases do so in a more elegant way …
46One-way compression function — In cryptography, a one way compression function is a function that transforms two fixed length inputs to an output of the same size as one of the inputs. The transformation is one way , meaning that it is difficult given a particular output to… …

48Perfect hash function — A perfect hash function for a set S is a hash function that maps distinct elements in S to a set of integers, with no collisions. A perfect hash function has many of the same applications as other hash functions, but with the advantage that no… …
49Ptolemy's table of chords — The table of chords, created by the astronomer and geometer Ptolemy in Egypt during the 2nd century AD, is a trigonometric table in Book I, chapter 11 of Ptolemy s Almagest,[1] a treatise on mathematical astronomy. It is essentially… …
50Inverse function — In mathematics, if fnof; is a function from A to B then an inverse function for fnof; is a function in the opposite direction, from B to A , with the property that a round trip (a composition) from A to B to A (or from B to A to B ) returns each… …
