For example, if you create a spreadsheet that analyzes product profitability based on the prices of various inputs, one important aspect of sharing the spreadsheet is to enable other users to change or enter new assumptions and view the results
are two buttons that manipulate spreadsheets in each edit window, similar to Excel. The first FitNesse spreadsheet converts the copy spreadsheet content to the FitNesse table. You must paste the spreadsheet contents into the edit window and click;The second button, FitNesse to a spreadsheet, is useful. After clicking
Google is launching a web-based spreadsheet program today that will allow people to view and simultaneously edit data, while conducting cting in-document chat. initially, the service will be available only to a limited number of users, and they wowould all need to have a Google account for the purpose.

The Code is as follows:

This function returns a more accurate addition result.Parameter: arg1: the first addition; the second addition

CSS filters to achieve the effect of frosted glassApple's IOS 7 brings us the "frosted glass" effect-a translucent, blurred element that looks like frosted windows. With the introduction of Apple, this effect can be seen in more and more places. It's a bit complicated to reproduce the effect--only fuzzy translucent images can be used to achieve the effect of the frosted glass before CSS filters. Currently, almost all mainstream bro

If ABS (xd)> ABS (YD) then check line gradient
Horizontal (ISH) lines
If x1> X2 then if line is back to front
Swap X1 and X2 then swap it round
Swap Y1 and Y2

Solve your external dependencies-SVN: externals
In daily project version management, we may need to put different repository in different directories, or put several repository together. most of the time, this is to solve the dependency in build, so this "personalized" structure should be shared and become a part of the version. otherwise, project members need to establish such struct

Public delegate int Calc (int a, int B); // defines a delegate class Calc
Suppose we have methods int add (int x, int y) and int Mul (int a, int B ). Assume that the two methods return the sum of the two numbers and the product of the two numbers.

the code we will find:When we are programming, this object relies on this class whenever "new" is an object. If you need to modify this class for some reason during the later maintenance process, the only way to do this is to open the source code, modify it, and modify all the operations associated with the object. This is very bad for us.The problem is: objects cannot respond to changes in "concrete instantiation types"Solution: Package change point, where changes, packaging where. In this exa

First, exception handlingIn the process of running the program, you will always encounter a variety of errors. Program An error stopped running, then we can not let the program stop running it, this time we need to catch the exception, by catching the exception, we do the corresponding processing.Let's begin by writing a function that implements the division operation.
