  2. Infix notation - Wikipedia

    en.wikipedia.org/wiki/Infix_notation

    Infix notation may also be distinguished from function notation, where the name of a function suggests a particular operation, and its arguments are the operands. An example of such a function notation would be S (1, 3) in which the function S denotes addition ("sum"): S(1, 3) = 1 + 3 = 4 .

  3. Common operator notation - Wikipedia

    en.wikipedia.org/wiki/Common_operator_notation

    An operator which is non-associative cannot compete for operands with operators of equal precedence. In Prolog for example, the infix operator :-is non-associative, so constructs such as a :- b :- c are syntax errors. Unary prefix operators such as − (negation) or sin (trigonometric function) are typically associative prefix operators.

  4. Calculator input methods - Wikipedia

    en.wikipedia.org/wiki/Calculator_input_methods

    Immediate-execution calculators are based on a mixture of infix and postfix notation: binary operations are done as infix, but unary operations are postfix. Because operators are applied one-at-a-time, the user must work out which operator key to use at each stage, and this can lead to problems.

  5. Operator-precedence parser - Wikipedia

    en.wikipedia.org/wiki/Operator-precedence_parser

    In computer science, an operator-precedence parser is a bottom-up parser that interprets an operator-precedence grammar.For example, most calculators use operator-precedence parsers to convert from the human-readable infix notation relying on order of operations to a format that is optimized for evaluation such as Reverse Polish notation (RPN).

  6. Prolog syntax and semantics - Wikipedia

    en.wikipedia.org/wiki/Prolog_syntax_and_semantics

    Examples of compound terms are truck_year('Mazda', 1986) and 'Person_Friends'(zelda,[tom,jim]). Compound terms with functors that are declared as operators can be written in prefix or infix notation. For example, the terms -(z), +(a,b) and =(X,Y) can also be written as -z, a+b and X=Y, respectively. Users can declare arbitrary functors as ...

  7. Shunting yard algorithm - Wikipedia

    en.wikipedia.org/wiki/Shunting_yard_algorithm

    The result for the above examples would be (in reverse Polish notation) "3 4 +" and "3 4 2 1 − × +", respectively. The shunting yard algorithm will correctly parse all valid infix expressions, but does not reject all invalid expressions. For example, "1 2 +" is not a valid infix expression, but would be parsed as "1 + 2". The algorithm can ...

  8. Binary operation - Wikipedia

    en.wikipedia.org/wiki/Binary_operation

    Binary operations are often written using infix notation such as , +, or (by juxtaposition with no symbol) rather than by functional notation of the form (,). Powers are usually also written without operator, but with the second argument as superscript .

  9. Operator (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Operator_(computer...

    Instead, the operation uses the special character > (which is tokenized separately during lexical analysis), and infix notation, as x > y. Common examples that differ semantically (by argument passing mode) are Boolean operations, which frequently feature short-circuit evaluation: e.g. a short-circuiting conjunction (X AND Y) that only ...
