derivative calculator

Python implements a simple arithmetic calculator, python I. Algorithms 1. The main idea of the algorithm is to convert an Infix expression into a Postfix expression, and then use the stack's simple data structure, returns the result of an expression. 2. The detailed description of how to convert a common expression to a suffix expression and how to process a suffix expression and calculate the result is not described here. Ii. Simple

One: IntroductionAt present, mobile phones can be said to be very high penetration of electronic equipment, because of its easy to carry, easy to use, affordable, and so on, now the mobile phone has begun to a certain extent to replace the call function of fixed telephone, as well as some of the original computer software functions. Mobile phone software has become rich with the development of mobile phones, today has appeared a lot of specialized in the production of mobile phone software compa

This article mainly introduces the simple triangle and rectangular perimeter area calculator implemented by PHP. The implementation in this article is relatively simple and provides code file download, if you need it, you can use PHP object-oriented knowledge to design a graphical calculator and abstract class knowledge. This calculator can calculate the circumfe

Some days ago, the teacher made a course design in Java and made a calculator (speechless) in two weeks ), The result is that the calculator is too simple and not challenging. It will be done in half a day, There is still a limit on the result time, and the previous method for finding large numbers is always unstable.AlgorithmImplemented, It can only process the addition and subtraction of two positiv

A small calculator that can calculate the value of a simple mathematical expression is not a compiler, but a knowledge of the compiler is used. I have been reading some compiler stuff recently. Therefore, writing this simplest calculator is an image of the abstract compiler knowledge, it also lays the foundation for adding complicated things-statements. This calculator
