ruby - Convert floating-point number to words

Question

How do I get the word-equivalent of a floating-point number? E.g.

• 10.24 → ten point twenty-four
• 5.113 → five point hundred and thirteen

Answer 1

有一个名为numbers_and_words的宝石！到目前为止，我已经在几个项目中使用它，没有任何问题。

Answer 2

使用语言宝石：

require 'linguistics'
Linguistics.use( :en )

p 10.24.en.numwords #=> "ten point two four"
p 5.113.en.numwords #=> "five point one one three"

或尝试按照此答案中的说明使用此技巧来获得更高的精度：

require "linguistics"
Linguistics::use(:en)

class Float
  def my_numwords
    self.to_s.split('.').collect { |n| n.en.numwords }.join(' point ')
  end
end

p 10.24.my_numwords #=> "ten point two four"
p 5.113.my_numwords #=> ""five point one hundred and thirteen"
