Generate a Random Word in Swift
(5 answers)
Closed 4 years ago.
I am trying to build a game in SpriteKit. which I planned to create some random words. I found some links but unfortunately, I am not able to figure out a solution.
Does anybody know of a way to generate a random word?
The easiest way would probably be to just make an Array of accepted random words and pick a random element.
let words = ["One", "Fish", "Two", "Fishes", "Red", "Blue"]
Swift 4.2: let word = words.randomElement()
Pre-Swift 4.2 Look at this question

I wrote this in rails console
(3352.3744333333334==3352.3744333333335) #true
and result was true
Notes:
I'm using ruby 2.4.0 and rails 5.0.1
I’m not an expert in ruby but my best answer is that the code is printing out all of the numbers but only comparing like the first 10 digits meaning 3352.374433 to 3352.374433 and it’s not going further than that. This would be the most logical explanation In my mind

Is there any way I can define a variable in LaTeX?

Is there a way to add a text by reference using LaTeX? I have several text references to 'versionXX.yy'. I wonder if I can define this in one place so I don't need to update it in all places.
Thanks
You could define a variable or new command with your version at the beginning and then just use this definition. See here
Btw. there is a special site called tex.stackexchange.com for this kind of questions.

How to make subscripts and superscripts using NSAttributedString?
(5 answers)
Closed 8 years ago.
I'm currently working in Xcode with objective-c.
I have an normal NSString with a string.
Let's say the string is "Hello Stackoverflow".
Now I want to make the "Hello" piece of the string superscript, how do I do that?
UPDATE:
I want to display it in a UItextview. I tried kCTSuperscriptAttributeName from the other post, but the UItextview won't allow "NSmutableattributedstring" or "NSattributedstring".
Well you can't as NSString only holds characters, not attributes about how those characters will be displayed.
That answers the question, however my answer can be enhanced if you tell us how you intend to display the string.
