Most operator-precedence parsers can be modified to produce postfix expressions ; in particular, once an abstract syntax tree has been constructed, the corresponding postfix expression is given by a simple post-order traversal of that tree.

In infix notation, unlike in prefix or postfix notations, parentheses surrounding groups of operands and operators are necessary to indicate the intended order in which operations are to be performed.

In terms of operator position, an operator may be prefix, postfix, or infix.

A prefix or postfix operator can be either associative or non-associative.

It is uncommon to have the registers be fully general purpose, because then there is no strong reason to have an expression stack and postfix instructions.

The position of the operator with respect to its operands may be prefix, infix or postfix.

Boolean NOT ( which returns the opposite of a given Boolean ) works the same as the if-then-else structure, with F and T as the second and third values, so it can be implemented as a postfix operation:

Boolean AND ( which returns T if both of the two Boolean values surrounding it are T ) works the same as an if-then-else structure with F as the third value, so it can be implemented as a postfix operation:

If the Diplom has been obtained at a University of Applied Sciences ( Fachhochschule ), usually the postfix "( FH )" has to be added.

If we first write it into postfix form, that is, < tt > 2 3 add 11 mul 1 add </ tt >,

Binary operations sometimes use prefix or ( probably more often ) postfix notation, both of which dispense with parentheses.

The term Polish notation is sometimes taken ( as the opposite of infix notation ) to also include Polish postfix notation, or Reverse Polish notation, in which the operator is placed after the operands.

* Reverse Polish notation or " postfix notation ", which places the operator after the operands, such as a b +

The above dialog only addresses greeting one person because some words change into multiple others e. g. " Wasuzotya " is the combination of a singular prefix ( Wa-you ), word ( sula-sleep ), and singular postfix ( otya-How did ) spoken as one with a plural form that subsequently becomes " Mwasuze mutya " which is composed of two distinct words emerging from two different plural prefixes, a word, and the plural form of the postfix.

A prefix or postfix operator is associative if and only if it may compete for operands with operators of equal precedence.

A similar concept underlies the reverse Polish notation ( RPN, a postfix notation ) of the Friden EC-130 calculator and its successors, many Hewlett Packard calculators, the Forth programming language, or the PostScript page description language.

The $ 395 HP-35, along with nearly all later HP engineering calculators, used reverse Polish notation ( RPN ), also called postfix notation.

Forth relies heavily on explicit use of a data stack and reverse Polish notation ( RPN or postfix notation ), commonly used in calculators from Hewlett-Packard.

Edsger Dijkstra invented the shunting-yard algorithm to convert infix expressions to postfix ( RPN ), so named because its operation resembles that of a railroad shunting yard.

The name " vodka " is a diminutive form of the Slavic word voda ( water ), interpreted as little water: root вод-( vod -) +-к-(- k -) ( diminutive suffix, among other functions ) +-a ( postfix of feminine gender ).

Common notations are prefix notation ( e. g. +, −, not ), postfix notation ( e. g. factorial: n!

It is not as simple to parse by computers as prefix notation ( e. g. + 2 2 ) or postfix notation ( e. g. 2 2 + ), but many programming languages use it due to its familiarity.

", digital electronics, Boolean algebra, computer numbering systems, recursive functions, data structures ( primarily dealing with heaps, binary search trees, stacks, and queues ), lisp programming, regular expressions and Finite State Automata, bit string flicking, graph theory, assembly programming and prefix / postfix / infix notation.

* RPN or traditional semi-algebraic ( infix data / algebraic operator entry / postfix one-number function entry ), user selectable

Because this defines T, F, NOT ( as a postfix operator ), OR ( as an infix operator ), and AND ( as a postfix operator ) in terms of SKI notation, this proves that the SKI system can fully express Boolean logic.

Maude lets the user specify whether or not operators are infix, postfix or prefix ( default ), this is done using underscores as place fillers for the input terms.

Oy ), a prefix / postfix indicating a Finnish Limited company

* Reverse Polish notation-( RPN ), also known as postfix notation ( 1920 )

A key distinction between analysis of algorithms and computational complexity theory is that the former is devoted to analyzing the amount of resources needed by a particular algorithm to solve a problem, whereas the latter asks a more general question about all possible algorithms that could be used to solve the same problem.
