Based on HTML + CSS, the simple calculator compiled by jQuery (added a keyboard listener) and cssjquery I have released a simple calculator. Today I made some modifications and added a keyboard listening event. You don't need to use the mouse to point it. JS Code: Var yunSuan = 0; // operator number, 0-no operation; 1-addition; 2-subtraction; 3-multiplication; 4-division var change = 0; // After the operato

RPN (reverse Polish Notation), a reverse polish expression. RPN calculator is a calculator that uses the reverse Polish notation method of user interaction, which is typically popular with people who deal with financial, engineering or other technical problems. 1) The function of the calculator: If no parentheses are used, input numbers are pushed into the stack.

for WCF, we have a theoretical foundation in front of Today, through an example of a calculator, we will explain how to create a complete WCF application step-by-step. One, create the entire solution Calculator.service: A class library project, Define service contract, apply System.ServiceModel assemblies, and provide implementations of WCF services. Calculator.host: A Windows Forms application that implements a homestay for a servic

Variables and types of tagsThe next step is to expand the calculator to handle variables with a single letter name, because there are only 26 letters (currently only in lowercase letters), so we can store variables in an array of 26 entries (called vbltable).To make the calculator more useful, you can also extend it to handle multiple expressions (one per line) and use floating-point values.Calculator lexic

This article mainly introduces the PHP programming to achieve a simple web version of the calculator function, involving PHP simple form operation and numerical computing related implementation skills, the need for friends can refer to the following How to use PHP code to implement a web version of the calculator simple function? The following is the PHP basic knowledge to do the web version of the

1. Overview There are a lot of vector computing tools in the toolbox of ArcGIS, and the grid has calculators, and it's easy to operate. Similar to the field calculator in vectors, it is calculated by constructing map algebra expressions. The Raster Calculator tool is used to create and execute map algebra expressions to output a new raster, and the built-in functions fall into the following categorie

Using MFC to make a simple calculator, to deepen the understanding of MFC learning, this calculator is based on the dialog box, the following to briefly explain how to make your own calculator1. First, click VS2012, launch the VS software, then build the application as shown, enter the project name below the diagram2. create a dialog-based standard program, as shown in the rest of the settings using System

The Set calculator assists java in processing Structured Text Data Reading, java structured JAVA only provides the most basic data reading functions such as specifying delimiters. Other common functions must be implemented at the underlying layer. For example: reads a specified column by column name, the sequence of the specified column, the specified data type, and no delimiter. Although it is not difficult to implement such functions in JAVA, the co

Python programming uses the tkinter module to implement the complete code example of the calculator software, pythontkinter Python provides libraries for multiple graphic development interfaces. Tkinter is one of them. Tkinter module (Tk Interface) is the interface of Python's standard Tk GUI toolkit. Tk and Tkinter can be used on most Unix platforms, and can also be used in Windows and Macintosh systems. Later versions of Tk8.0 can implement the loca

Simple factory mode-MFC calculator implementation (continuous operation) The design pattern is the goal of refactoring. It plays an important role in code reuse and expansion. The importance of restructuring and design patterns is self-evident in learning object-oriented models. Then, the learning design model should be combined with software design and software coding, and driven by examples. This article will learn the simple factory mode through th

principle:1. Change the expression of the middle order to an expression2. The current character is a number, put that number in the stack3. The current character is an operator, take out two trees from the stack, operate from the operator, and put the results of the operation into the stack4. Repeat until the character is finished. Only one element is left in the stack, that is, the result of the operation PS: I did not deal with it. Only be able to perform operations within 10, assuming there i

Under Linux, there is a command-line calculator: BC. The program is generally released with the release.The BC Calculator is capable of performing some basic calculations, including +,-,x,\,%.These calculations are not for decimal, and can be binary, octal, hexadecimal, and can be mixed!StartWhen you start, enter the BC command at the terminalExitYou can use Ctrl+d when exiting, or you can enter quit.Precis

principle:1. Change the middle order expression to follow-up expression2. The current character is a number, put that number in the stack3. The current character is the operator, take out two trees from the stack, according to operator operation, put the result of the operation into the stack4. Repeat until the character is finished, and there is only one element left in the stack, that is, the result of the operation PS: I do not handle, can only run 10 of the operation, if necessary can be ext
