 # /Zc:rvalueCast (Enforce type conversion rules)
 
-When the **/Zc:rvalueCast** option is specified, the compiler correctly identifies an rvalue reference type as the result of a cast operation in accordance with the C++11 standard. When the option is not specified, the compiler behavior is the same as in Visual Studio 2012.
+When the **`/Zc:rvalueCast`** option is specified, the compiler correctly identifies an rvalue reference type as the result of a cast operation. Its behavior conforms to the C++11 standard. When the option is unspecified, the compiler behavior is the same as in Visual Studio 2012.
 
 ## Syntax

+> **`/Zc:rvalueCast-`**
 
 ## Remarks
 
-If **/Zc:rvalueCast** is specified, the compiler follows section 5.4 of the C++11 standard and treats only cast expressions that result in non-reference types and cast expressions that result in rvalue references to non-function types as rvalue types. By default, or if **/Zc:rvalueCast-** is specified, the compiler is non-conformant and treats all cast expressions that result in rvalue references as rvalues. For conformance and to eliminate errors in the use of casts, we recommend that you use **/Zc:rvalueCast**.

-By default, **/Zc:rvalueCast** is off (**/Zc:rvalueCast-**). The [/permissive-](permissive-standards-conformance.md) compiler option implicitly sets this option, but it can be overridden by using **/Zc:rvalueCast-**.

-Use **/Zc:rvalueCast** if you pass a cast expression as an argument to a function that takes an rvalue reference type.
