Hey, just a question out of interest:

I recently created a sinatra project and used ruby-i18n in it. I  
noticed that there are yaml files for date formats (and also numbers)  
in the rails-i18n project.  
They worked out of the box for dates.

So I wondered if there are number format helpers, and although the  
formats are in the above mentioned files,  
the helpers are in ActiveView:

> **[ActionView::Helpers::NumberHelper](https://api.rubyonrails.org/classes/ActionView/Helpers/NumberHelper.html)**
>
> Provides methods for converting numbers into formatted strings. Methods are provided for phone numbers, currency, percentage, precision, positional notation, file size, and pretty printing.

So to use them with a standalone ruby project you have to extract it.  
Is there a reason behind that? Wouldn’t it make sense to include this  
in ruby-i18n or rails-i18n?

Just wondering about the reasons  
Thanks,  
Christoph
