instance method number_to_rounded

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). 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).

Examples

number_to_rounded(111.2345)                                  # => "111.235"
number_to_rounded(111.2345, precision: 2)                    # => "111.23"
number_to_rounded(13, precision: 5)                          # => "13.00000"
number_to_rounded(389.32314, precision: 0)                   # => "389"
number_to_rounded(111.2345, significant: true)               # => "111"
number_to_rounded(111.2345, precision: 1, significant: true) # => "100"
number_to_rounded(13, precision: 5, significant: true)       # => "13.000"
number_to_rounded(13, precision: nil)                        # => "13"
number_to_rounded(389.32314, precision: 0, round_mode: :up)  # => "390"
number_to_rounded(111.234, locale: :fr)                      # => "111,234"

number_to_rounded(13, precision: 5, significant: true, strip_insignificant_zeros: true)
# => "13"

number_to_rounded(389.32314, precision: 4, significant: true) # => "389.3"
