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(100, format: "%n  %")                       # => 100  %

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