number_to_percentage

Formats a number as a percentage string (e.g., 65%). You can customize the format in the options hash.

Options

• :locale - Sets the locale to be used for formatting (defaults to current

  locale).
  

• :precision - Sets the precision of the number (defaults to 3).

• :significant - If true, precision will be the # of significant_digits. If false,

  the # of fractional digits (defaults to +false+).
  

• :separator - Sets the separator between the fractional and integer digits (defaults

  to ".").
  

• :delimiter - Sets the thousands delimiter (defaults to “”).

• :strip_insignificant_zeros - If true removes insignificant zeros after the decimal separator

  (defaults to +false+).
  

• :raise - If true, raises InvalidNumberError when the argument is invalid.

Examples

number_to_percentage(100)                                        # => 100.000%
number_to_percentage("98")                                       # => 98.000%
number_to_percentage(100, :precision => 0)                       # => 100%
number_to_percentage(1000, :delimiter => '.', :separator => ',') # => 1.000,000%
number_to_percentage(302.24398923423, :precision => 5)           # => 302.24399%
number_to_percentage(1000, :locale => :fr)                       # => 1 000,000%
number_to_percentage("98a")                                      # => 98a%

number_to_percentage("98a", :raise => true)                      # => InvalidNumberError
