number_with_precision(number, options = {}) public

Formats a number with the specified level of :precision (e.g., 112.32 has a precision of 2 if :significant is false, and 5 if :significant is true). 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)

Examples

number_with_precision(111.2345)                                            # => 111.235
number_with_precision(111.2345, :precision => 2)                           # => 111.23
number_with_precision(13, :precision => 5)                                 # => 13.00000
number_with_precision(389.32314, :precision => 0)                          # => 389
number_with_precision(111.2345, :significant => true)                      # => 111
number_with_precision(111.2345, :precision => 1, :significant => true)     # => 100
number_with_precision(13, :precision => 5, :significant => true)           # => 13.000
number_with_precision(111.234, :locale => :fr)                             # => 111,234
number_with_precision(13, :precision => 5, :significant => true, :strip_insignificant_zeros => true)
# => 13
number_with_precision(389.32314, :precision => 4, :significant => true)    # => 389.3
number_with_precision(1111.2345, :precision => 2, :separator => ',', :delimiter => '.')
# => 1.111,23

Separator default is not always "." but depends on locale

Locale en:

number_with_precision(111.2345)  # => 111.235

Locale fr-FR:

number_with_precision(111.2345)  # => 111,235

Same with delimiter.
