number_with_precision

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 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).

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

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
