Looks like it does a subset of what the native Window.Intl does, a shame so few developers know about window.Intl...

Still, nice effort! I like it

double051• 12 years ago

I didn't know about that until now. Here's a neat blog post on the subject - http://marcoscaceres.github.io/jsi18n/

That said, numeral.js doesn't look like just subset, it's got a nice interface to work with, and you don't have to worry about cross-browser inconsistency. You just have to believe this library does everything correctly for each language/locale.

That's probably because most developers care about compatibility.

Gmo2• 12 years ago

Surely, you mean, most developers only care about compatibility with Chrome ?

With shimmable APIs?

felxh• 12 years ago

Thanks, I learned something new! But yeah, as other people have pointed out, browser support starts with IE 11 and almost no mobile browser supports it - so it might as well not exist.

clarkdave• 12 years ago

Intl is rather excellent, and if you do want to use it there's an nice shim for it here: https://github.com/andyearnshaw/Intl.js

I've been using this with great results so far. It works well with a loader (e.g. yepnope) as Chrome and Firefox support it natively, as does IE11.

inglor3• 12 years ago

Thanks for the shim, I was looking for that - very useful and passes all my tests in IE10.

How do I do Indian-style comma formatting with Numeral.js? Like so: 10,00,00,000, with thousands grouped in three digits and everything else in two digits.

sidmkp96• 12 years ago

Exactly what I was also thinking.

kaishiro• 12 years ago

I in no way mean for this to be disrespectful, but boy that looks confusing to my Western brain.

sdrothrock• 12 years ago

Japanese numbers used to be delimited with commas every four digits, like so: 1,0000,0000 due to the largest common single-use (i.e., not a combination of a small number plus a large number as in "hundred thousand") being 10,000 (万, man).

Nowadays I've only ever seen US-style commas and it's hard to even find a reference to the four-digit commas online.

10000 '0,0.0000' 10,000.0000

Because you know, why implement UTS #35? It exists and covers dozens of cultural contexts and that's no fun.

roryokane• 12 years ago

UTS #35 is Unicode Technical Standard #35, Unicode Locale Data Markup Language (LDML), http://www.unicode.org/reports/tr35/.

masklinn2• 12 years ago

Yep, more specifically (for this situation) numbers and currencies formatting (and format patterns)[0] and the related data in the CLDR (the LDML defines the CLDR's structures, the CLDR itself holds locale data such as the actual patterns and specific translated terms)

Looks very cool, although I wish they used more Excel-like number formats (http://office.microsoft.com/en-us/excel-help/number-format-c...)

Shameless plug: as part of the in-browser XLS parsing, we built a library for formatting numbers: https://github.com/SheetJS/ssf

porker• 12 years ago

Another similar library: http://josscrowcroft.github.io/accounting.js/

Used on many projects, works well.

Thanks for sharing! Unfortunately, bytes representations are wrong.

As you may now, there is a difference between kilobytes (KB) and kibibytes (KiB), megabytes (MB) and mibibytes (MiB) et cetera. 1 KiB = 1024 bytes = 1.024 KB.

Please check out https://en.wikipedia.org/wiki/Binary_prefix and fix your library :)

scotth• 12 years ago

That convention is not universally recognized.

peterashford• 12 years ago

...or barely recognised at all?

rglover• 12 years ago

Handy. Thanks!

A jQuery plugin that does formatting in a more jQuery-like manner can be found here - https://code.google.com/p/jquery-numberformatter/

It aims to mimic how number formatting is done on the server.

imjoshdean• 12 years ago

You know, I was looking at this and thinking "you know, this needs to be more jQuery-er!"

c.add(10).value();

No, numbers aren't (shouldn't be) treated as objects.
