number_with_precision(number, *args) public

Formats a number with the specified level of :precision (e.g., 112.32 has a precision of 2). You can customize the format in the options hash.

Options

  • :precision - Sets the level of precision (defaults to 3).
  • :separator - Sets the separator between the units (defaults to ".").
  • :delimiter - Sets the thousands delimiter (defaults to "").

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(1111.2345, :precision => 2, :separator => ',', :delimiter => '.')
 # => 1.111,23

You can still use number_with_precision with the old API that accepts the precision as its optional second parameter: 

  number_with_precision(number_with_precision(111.2345, 2)   # => 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.
