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). Keeps the number’s precision if nil.

• :round_mode - Determine how rounding is performed (defaults to :default. See BigDecimal::mode)

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

• :format - Specifies the format of the percentage string The number field is %n (defaults to “%n%”).

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)                                # => "1000,000%"
number_to_percentage(1000, precision: nil)                             # => "1000%"
number_to_percentage('98a')                                            # => "98a%"
number_to_percentage(100, format: '%n  %')                             # => "100.000  %"
number_to_percentage(302.24398923423, precision: 5, round_mode: :down) # => "302.24398%"
