number_with_precision
rails latest stable - Class:
ActionView::Helpers::NumberHelper
number_with_precision(number, options = {})public
Delegates to ActiveSupport::NumberHelper#number_to_rounded.
Additionally, supports a :raise option that will cause InvalidNumberError to be raised if number is not a valid number:
number_with_precision("12x34") # => "12x34" number_with_precision("12x34", raise: true) # => InvalidNumberError
1Note
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.
