template <class Type>
struct arithmeticOperatorsForType
{
/*...*/
template <Type Value1, Type Value2>
using Multiplies2 = multipliesValue<Type, Value1, Value2>;
/*...*/
};Creates multipliesValue (see multipliesValue) acting on type Type. Allows for multipliesValue to act as binary value operator.
-
Value1- value to be multiplied withValue2. -
Value2- value to be multiplied withValue1.
-
value- holds result of multiplication ofValue1withValue2.
-
value_type- type of fieldvalue. May not beTypebut should be castable to this type.
-
constexpr operator value_type () const noexcept- casts whole object to itsvalue_typereturningvalue.
