This calculator is made up of two parts: a mxml file with a foreground interface, a background controller as file. The Mxml file is responsible for displaying the calculator interface, which handles the information sent by the user and calculates the results. In this tutorial we mainly study:

The Panel container
The Label element
The Grid container

In reality, we often face a similar situation, perhaps a friend married, perhaps a long holiday to travel. Anyway, the situation is similar, is to know a specific date, you need to calculate the actual number of days from now. In general, the simplest and stupidest way is to take a calendar and count it day by day. Of course if you are using Windows 7, congratulations, no more days to get cramps, because we already have a simpler way-"calculator."

A small calculator made with bat/batch processingThis is my own bat/batch of small calculator, the following code directly copied into Notepad to save the. bat format can be used.
Support formulas, such as input: 12+12/(7-5), but only integer calculations are supported, decimals are not supported.
The utility is not very big, the technical content is not very high, but the process control is still good. Thi
Calculator and Windows System companion for many years, Win7 genuine system naturally also have calculator, compared with XP, Vista and earlier Windows system, Win7 Genuine System Calculator function is more powerful, in addition to simple add, subtract, multiply, divide, still can carry on more complex mathematics operation, As well as the various calculations e
Recently I used javascript to write a simple calculator. It seems okay to test it myself. The Code has been commented out. It is very good. I suggest you learn it. Recently I wrote a simple calculator in javascript, and it feels okay to test it on my own. Let's take a look at the interface:
The interface is like this, but what is the function?
Now it's just a simple standard
Look at the calculator in your phone and divide it into a general calculator and a science calculator
Think that the head is not big enough to achieve a normal version of the bar (support positive and negative subtraction, such as basic continuous operations, does not provide parentheses function)
Look at the diagram effect:

Win8 system is the most subversive of a system, the original Start menu is missing, many users often use the gadget also disappeared, perhaps hidden in the computer somewhere, but we are difficult to find, such as computer functions. Computer is our usual use of tools, we have been in the beginning of the menu to look up, and now even the beginning of the menu is not, so that win8 users are really not accustomed to ah, the following small set to teach everyone three methods, can quickly find the

When it comes to Win7 systems, it is believed that many novel features are profound, whether it is a highly flexible Win7 desktop, or a handy Win7 tool that can help us solve problems easily. The use of WINDOWS7 system has been two years, like the reason for Win7 is safe and stable and efficient, sometimes even a seemingly obscure tool or small function can bring great convenience, such as the Win7 system included in the calculator is such a tool. If
Do not know how many of the use of MAC students use the MAC native Calculator application? What about the Mac calculator shortcuts? It looks like a single calculator in fact it also has two other calculator models built into it, the scientific calculator and the programmer

Now it's just a simple standard calculator that can perform addition, subtraction, multiplication, division, and remainder operations. If the divisor is zero, the following prompt is displayed, as shown in the following figure:
1. Quick calculator Mode
In emacs23, you can use the M-x quick-Calc command or the shortcut key C-x * Q to start the quick calculator mode. This is a very small tool. After it is started, it will prompt the input mathematical formula in minibuffer, and press enter to display the result. This mode can be easily used for some basic mathematical operations, which is more convenient and quicker than using the b
Today, when I read "Compiling principles and practices", I saw a simple integer calculator implementation.Following the book's thinking, I expanded slightly:1. Extend from the integer calculator to the decimal calculator.2. Support Division3, support null characters.The results are as follows:The code is simple, as follows:CAL.C:#include The idea of program reali

Enter the Win8.1 Start screen interface and click the down arrow at the bottom to enter more options, as shown in the following image:
After that we can quickly find the calculator in more options, click Open, as shown in the following image:
Method Two: Use Win8.1 powerful search function to quickly find calculator
In Win8.1 any

1. BC Instruction addition,
4. BC Instruction Division (advanced), shown, 10/3 is 3, because we do not specify a decimal point after a few, the default is taken to the integer part, and 10/100 is zero, the same reason, only to take the integer 0 part. Use the "scale=[number" command to specify a few points after the decimal point:The BC Command calculates the remainder,
6. BC Command Count index,
