Ruby-on-rails 数字到英文单词转换 Rails

Number to English Word Conversion Rails

提问by Palani Kannan

Anybody knows the method to convert the numericals to english number words in rails?

有人知道在rails中将数字转换为英文数字单词的方法吗？

I found some Ruby scripts to convert numbericals to english words for corresponding words.

我找到了一些 Ruby 脚本来将数字转换为对应单词的英文单词。

Instead of writing a script in ruby, i feel that direct function is available.

不是用ruby写脚本，我觉得直接函数是可用的。

Eg. 1 -> One, 2 -> Two.

例如。1 -> 一，2 -> 二。

No, you have to write a function yourself. The closest thing to what you want is number_to_human, but that does not convert 1to One.

不，你必须自己写一个函数。与您想要的最接近的是number_to_human，但这不会转换1为One.

You can also use the to_wordsgem.

您还可以使用to_wordsgem。

This Gem converts integers into words.

这个 Gem 将整数转换为单词。

e.g.

例如

1.to_words # one ,

100.to_words # one hundred ,

101.to_words # one hundred and one

It also converts negative numbers.

它还转换负数。

How about this? Written for converting numbers to words in the Indian system, but can be easily modified.

这个怎么样？用于在印度系统中将数字转换为单词，但可以轻松修改。

def to_words(num)
  numbers_to_name = {
      10000000 => "crore",
      100000 => "lakh",
      1000 => "thousand",
      100 => "hundred",
      90 => "ninety",
      80 => "eighty",
      70 => "seventy",
      60 => "sixty",
      50 => "fifty",
      40 => "forty",
      30 => "thirty",
      20 => "twenty",
      19=>"nineteen",
      18=>"eighteen",
      17=>"seventeen", 
      16=>"sixteen",
      15=>"fifteen",
      14=>"fourteen",
      13=>"thirteen",              
      12=>"twelve",
      11 => "eleven",
      10 => "ten",
      9 => "nine",
      8 => "eight",
      7 => "seven",
      6 => "six",
      5 => "five",
      4 => "four",
      3 => "three",
      2 => "two",
      1 => "one"
    }

  log_floors_to_ten_powers = {
    0 => 1,
    1 => 10,
    2 => 100,
    3 => 1000,
    4 => 1000,
    5 => 100000,
    6 => 100000,
    7 => 10000000
  }

  num = num.to_i
  return '' if num <= 0 or num >= 100000000

  log_floor = Math.log(num, 10).floor
  ten_power = log_floors_to_ten_powers[log_floor]

  if num <= 20
    numbers_to_name[num]
  elsif log_floor == 1
    rem = num % 10
    [ numbers_to_name[num - rem], to_words(rem) ].join(' ')
  else
    [ to_words(num / ten_power), numbers_to_name[ten_power], to_words(num % ten_power) ].join(' ')
  end
end
