In infix notation, we need parentheses to show which part of the expression to solve first. In postfix notation, the order of operations is already clear, so we don’t need parentheses.

A scientific calculator program that gets infix expressions from input, converts them to postfix and prefix notation, and shows the result by evaluating the postfix expression.

Abstract: In Computer Science, Reverse Polish notation has simplified calculations and has benefited a new face to technology. Since 1960, RPN is used in calculators because its implementation is very ...

We present several algorithms for evaluating point containment in constructive solid geometry (CSG) trees with unbounded primitives. Three algorithms are presented based on postfix, prefix, and infix ...

With version 4.0, the open source project Langium has released a range of new functions, including support for infix operators. This extension is intended not only to simplify the definition of ...
