template <class Type, Type ... Values> struct dividesValue;Returns division of Values... in order of their appearance. If Values... is empty, this operator is not defined.
-
Type- type of values to operate on. -
Values...- set of values to operate on. If this set is empty whole operation is not defined. If set is single element then whole operation is evaluated to that element.
value - holds result of operation. If Values... is single element, value holds that element.
value_type - type of field value. May not be Type but should be castable to this type.
constexpr operator value_type () const noexcept - casts whole object to its value_type returning value.
