Read more programming tutorials and developer tool reviews. That should help you keep it all straight, too. Just keep it all straight by remembering that only the double equal sign means “is equal to” and the single equal sign can be roughly translated into “is.” You will also see a single equal sign being used to denote variables and the like. Notice the line above that uses the single equal sign? It is saying the parent location is nspage.html. I’m sure there’s a better way of putting it, but that’s how I keep it all straight. Notice the line above involving the double equal sign? It is saying if the navigator application name is equal to Internet Exploder. A double equal sign means “ is equal to.”.Type ne or neq for Does Not Equal () With that option turned on in Word, you can now type the following to insert the does not equal sign. Choose Use Math AutoCorrect outside of Math regions. Without getting into a lot of programming mumbo jumbo, here’s the basic difference (and this always did seem backward to me). Inside the AutoCorrect dialog box: Select the Math AutoCorrect option at the top. I would like to sum weights for only those cells that has values in first column. Now, to us humans, one or two equal signs do not make for a big difference, but to a JavaScript-reading computer, it signifies a great deal of difference. I have another column by name weights that has values in all cells. Notice the first use of the equal sign doubles it up and the second is the more traditional single equal sign.

Just keep it all straight by remembering that only the double equal sign means is equal to and the single equal sign can be roughly translated into is. I want you to look at two uses of the equal sign within the script: (navigator.appname = "Internet Exploder") You will also see a single equal sign being used to denote variables and the like. Every time a new expression without an equal sign is evaluated, the value saved in ans will be overwritten. Let’s take a quick look at the following JavaScript: T or F: If an expression without an equal sign is typed into the Command Window, MATLAB will evaluate it and store the result in a special variable called ans. Today we are going to look at a rather small but quite important command in most high-level programming languages, such as Python, Java, and C# – the equal sign or =.
