I have an application that generate invoices. The system works with three currencies: Pounds, US Dollars and Euros. As part of the requirements, invoices must have the total amount displayed in english words.
For example:
£100.50 - One hundred Pounds and fifty pences.
$100.50 - One hundred US Dollars and fifty cents.
€100.50 - One hundred Euros and fifty cents.
I found this post from 2010, but It doesn't really solve my problem.
I would like to know what is the best way to convert numbers into words including the currency.
I am trying to find a gem to help me on this matter, but I could find...
Any suggestion is very welcome.
The post you linked mentions linguistics.gem - since it can convert the numbers for you, all you need to do is split out the major and minor units (i.e. dollars and cents/pounds and pence), process each, then recombine into a string with the major and minor unit names, i.e.
majorUnit.en.numwords dollars [and minorUnit.en.numwords cents]
...
puts 100.en.numwords + " dollars and " + 50.en.numwords + " cents"
# => 100 dollars and fifty cents
A bonus of linguistics.gem is that it can also handle singular/plural for you for when you have only one of your major/minor units, eg.:
"penny".en.plural
# => "pence"
