How do I put commas in numbers?

Does anyone know how to take a string of numbers:

68431351

And have it displayed as: 68,431,351.00

Basically add commas?

And decimal .00 at the end.

PS I'm a noob, so please explain this to me as if i'm 5! Cheers.

it is not as easy as you would think.

here is a recent thread where someone asked the same question:

https://www.construct.net/en/forum/construct-3/how-do-i-8/put-dot-number-157309?kws=regex%2bcomma

and here is an older thread where I give an example using regex:

Cheers! very helpful.

I thought this would be a fun and quick little exercise. It wasn't and now my brain hurts.

Note that this breaks when dealing with really large numbers. The editor itself breaks too, so I don't know if its a bug or a hard limitation.

I'm a bit of a newcomer to game programming so I apologize for the dumb question but is this (adding comma's) a major obstacle with other game engines? It seems like something that should be easy to include in a game engine and not require so much time to put a formatting function in.

It is a fairly common question.

It's solved by regex already, so it's not something that engine developers normally go out of their way to specifically add in after already supporting regex.

Also, while it can be difficult for a beginner to think through it, it wouldn't be hard for an experienced developer to put it together in half an hour with the math tools provided, which you can then utilize. That's all libraries and behaviours and plugins are in the programming world: people who have put together ready to use code so you don't have to yourself.

I personally had some difficulty because I ran into exceptions and cases where my approach would break or not work, due to my unfamiliarity and lack of research on how other people did it before trying to tackle the problem. But programming can always evolve. I'm thinking of I can clean it up, turn it into a function with parameters, and make sure there aren't any buggy situations, I could probably submit it as a feature request and get it added as an expression. (Alternatively make it an addon, copy and paste able function/event, or JavaScript library, ect.)

Now that I actually look and research a bit, of course it's already been done before. stackoverflow.com/questions/1990512/add-comma-to-numbers-every-three-digits

I guess my confusion came from seeing HTML having to be used for everything web related years and years ago to more user-friendly approaches like Wordpress (not for all sites, talking easy to use tools).

I just figured somewhere along the way, there would be an option/check-box, short code, etc that changed the format to include commas in numbers that were greater than 3 digits.

Again, I appreciate your explanation and will come back to this at some point when it doesn't seem so overly complex. Take care!

Did you look at AllenR's example?

Set text to RegexReplace( str(int(num)), "(\d)(?=(\d{3})+(?!\d))", "g", "$&,")

-> Text: Append "."
-> Text: Append int(abs(num)×10)%10
-> Text: Append round(abs(num)×100)%10

Another (commented) way to do this string manipulation using a function.

This is a deceptively complex problem, fortunately you don't have to do any of it. With a little script you can take advantage of the Intl object, which is provided by modern browsers.

It has a lot of interesting features geared towards translating strings, the one of interest is the number formatter.

Here is an example, that formats a number according to the English language. It has many more options.

Then add

-> Text: Append round(abs(num)×100)%10

to pad the decimals.

I don't quite understand how it works. more precisely, I did not understand how it works at all. but it works! thank you!!!
