Calculator.NET is an advanced Windows calculator that provides the ability to perform complex mathematical equations. The application uses RPN (Reverse Polish Notation) which brings a wide range of features and benefits as follows: As a postfix expression is scanned from left to right, operands are simply placed into a last-in, first-out (LIFO) stack and operators may be immediately applied to the operands at the bottom of the stack. Using RPN, it is possible to express any complex calculation without using parentheses at all. Also, because subexpressions are evaluated as they are entered, entry errors are more obvious with RPN. By contrast, on an algebraic calculator, omitting an opening pa...Read more about Calculator.NET
