Web6) If conversion of expression to new_type involves lvalue-to-rvalue, array-to-pointer, or function-to-pointer conversion, it can be performed explicitly by static_cast. 7) Scoped enumeration (C++11) type can be converted to an integer or floating-point type. When the target type is cv bool, the result is false if the original value is zero and ... WebTo create an instance of a specific unit, we create an instance of its container type: // The variable speed has a value of 5 meters per second. units::meter_per_second_t speed{5.0}; Alternatively, the units library has type literals defined for some of the more common container types. These can be used in conjunction with type inference via ...
