_Ty _Old_val = static_cast<_Ty&&>(_Val);

>(_Old_val)

This is a C++ code that demonstrates the use of the static_cast operator to convert a value from one data type to another.

In this case, the operator is used to convert a value stored in the variable _Old_val to the data type _Ty. The result of the conversion is stored in a new variable of the same data type.

The static_cast operator is a type of explicit type conversion in C++. It is used to convert one data type to another, with the compiler checking that the conversion is safe at compile-time. This helps to ensure that the program will behave correctly and avoid run-time errors.

Overall, the static_cast operator is a powerful tool for handling type conversions in C++, and is commonly used in a wide variety of applications.
