数字(货币)转换成英文单词 [英] number (currency) into english words

问题描述

我有一个生成发票的应用程序.该系统使用三种货币:英镑、美元和欧元.作为要求的一部分，发票必须用英文显示总金额.

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.

例如:
100.50 英镑 - 一百英镑五十便士.
100.50 美元 - 一百美元五十美分.
€100.50 - 一百欧元五十美分.

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.

推荐答案

您链接的帖子提到了languages.gem - 因为它可以为您转换数字，您需要做的就是拆分主要和次要单位(即美元和美分/磅和便士)，分别处理，然后重新组合成一个带有主要和次要单位名称的字符串，即

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

linguistics.gem 的一个好处是它也可以处理单数/当您只有一个主要/次要单元时，您可以使用复数形式，例如:

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"
