Refimprove date March 2010 In mathematics , a unaryoperation is an Operation mathematics operation with only one operand , i.e. a single input. Specifically, it is a function math f A to A math where A is a Set mathematics set . In this case f is called a unaryoperation on A . Common notations are prefix notation e.g. , , not , postfix notation e.g. factorial n , functional notation e.g. sin x or sin x , and superscript s e.g. transpose A sup T sup . Other notation exists as well, for example in the case of the square root a horizontal bar over the argument extending the square root sign can indicate the extent of the argument. Unary negative and positive As unary operations have only one operand they are evaluated before other operations containing them. Here is an example using negation 3 2 Here the first represents the binary subtraction operation, while the second represents the unary negation of the 2. Therefore, the expression is equal to 3 2 5 Technically there is also a unary positive but it is not needed since we assume a value to be positive 2 2 Unary positive does not change the sign of a negative operation 2 2 In this case a unary negative is needed to change the sign 2 2 Computer programming Unary operators called monadic in APL programming language APL are also used in programming languages .

A unary function is a function mathematics function that takes one Parameter computer science argument . In computer science , a unary operator is a subset of unary function. Example a here a is an operand which is operated by a unary operator . it can be written in the form a a 1. Many of the elementary function s are unary functions, in particular the trigonometric functions , logarithm with a pre specified base, exponentiation to a pre specified power or from a pre specified base, and hyperbolic function are unary.

In computational complexity theory , a unary language or tally language is a formal language a set of string computer science strings where all strings have the form 1 sup k sup , where 1 can be any fixed symbol. For example, the language 1, 111, 1111 is unary, as is the language 1 sup k sup k is prime number prime . The complexity class of all such languages is sometimes called TALLY . The name unary comes from the fact that a unary language is the encoding of a set of natural number s in the unary numeral system . Since the universe of strings over any finite alphabet is a countable set , every language can be mapped to a unique set A of natural numbers thus, every language has a unary version 1 sup k sup k in A . Conversely, every unary language has a more compact binary version, the set of binary encodings of natural numbers k such that 1 sup k sup is in the language. Since complexity is usually measured in terms of the length of the input string, the unary version of a language can be easier than the original language. For example, if a language can be recognized in O 2 sup n sup time, its unary version can be recognized in O n time, because replacing every symbol with a 1 has made the language size logarithmically smaller. More generally, if a language can be recognized in O f n time and O g n space, its unary version can be recognized in O n f log n time and O g log n space we require O n time just to read the input string . However, if membership in a language is Recursive language undecidable , then membership in its unary version is also undecidable. Relationships to other complexity classes TALLY is contained in P poly , with a single bit advice string for each input length k specifying whether 1 sup k sup is in the language or not. A unary ... n and at most n values of length at most n , but not all sparse languages are unary thus TALLY is contained in SPARSE . Piotr Berman showed in 1978 that if any unary language is NP complete , then P ... more details
Unary coding , sometimes called thermometer code , is an entropy encoding that represents a natural number , n , with n ones followed by a zero if natural number is understood as non negative integer or with n &minus 1 ones followed by a zero if natural number is understood as strictly positive integer . For example 5 is represented as 111110 or 11110. Some representations use n or n &minus 1 zeros followed by a one. The ones and zeros are interchangeable without loss of generality. table border 1 cellpadding 2 tr th n non negative th n strictly positive th Unary code th Alternative tr td 0 td 1 td 0 td 1 tr td 1 td 2 td 10 td 01 tr td 2 td 3 td 110 td 001 tr td 3 td 4 td 1110 td 0001 tr td 4 td 5 td 11110 td 00001 tr td 5 td 6 td 111110 td 000001 tr td 6 td 7 td 1111110 td 0000001 tr td 7 td 8 td 11111110 td 00000001 tr td 8 td 9 td 111111110 td 000000001 tr td 9 td 10 td 1111111110 td 0000000001 table Unary coding is an optimally efficient encoding for the following discrete probability distribution math operatorname P n 2 n , math for math n 1,2,3,... math .

For example, using the symbol a tally mark , the number 6 is represented as . The Western standard method cn date April 2012 of counting on one s fingers is effectively a unary system.

The sets X sub j sub are the called the domains of the operation, the set Y is called the codomain of the operation, and the fixed non negative integer k is called the arity of the operation. An operation of arity zero, called a nullary operation, is simply an element of the codomain Y . An operation of arity k is called a k ary operation. Thus a k ary operation is a k 1 ary relation mathematics relation that is functional on its first k domains. Elements of the functional domains are called arguments . Elements of the codomain are called values . An operation is often called an operator , though other users of the term may reserve it for more specialized uses. At any rate, the arguments are also called operands or inputs , and the values are also called results or outputs .
