Instance Method Details

#money_maker(number, options = {}) ⇒ Object

Similar to Rails’ number_to_currency, but we don’t want to rely on Rails. Found the majority of this code online, but lost the URL. If this is yours, let me know and I’ll give credit.

Formats the number into a currency format. You can customize the format in the options hash.

Options

  • :currency_symbol - Currency symbol. (default is ‘$’)

  • :delimiter - Thousands separator. (default is ‘,’)

  • :decimal_symbol - Separates integer and fractional amounts (think dollars and cents). (default is ‘.’)

  • :currency_before - Boolean to set placement of :currency_symbol. true for before number, false for after number. (default is true)

  • :after_text - Useful for displaying the currency after the number. (default is ‘ USD’)

Example

money_maker(1000)     # => $1,000.00 USD
money_maker(1000, :delimiter => '.', :decimal_symbol => ',', :after_text => '')    # => $1.000,00

  # split integer and fractional parts

  # insert delimiters
  int.gsub!(/(\d)(?=(\d\d\d)+(?!\d))/, "\\1#{options[:delimiter]}")
  
  return options[:currency_symbol] + int + options[:decimal_symbol] + frac + options[:after_text] if options[:currency_before]
  int + options[:decimal_symbol] + frac + options[:currency_symbol] + options[:after_text]
