For more information about types and primitives, see also the JavaScript data structurepage. If called from within a function, the return statement immediately ends execution of the current function, and returns its argument as the value of the function call. The isinstance() built-in function is recommended for testing the type of an object, because it takes subclasses into account. Example. If it is off, then number is nullable.. a function-try-block for a function with the return type (possibly cv-qualified) void; without encountering a return statement, return; is executed. The return type given in the function definition must match the return type in declarations of the function elsewhere in the program.

The identity function on M is clearly an injective function as well as a surjective function, so it is also bijective. If specified, a given value is returned to the function caller. In many programming languages (especially statically-typed programming languages such as C, C++, Java) the return type must be explicitly specified when declaring a function. Use the CREATE FUNCTION statement to create a standalone stored function or a call specification.. A stored function (also called a user function or user-defined function) is a set of PL/SQL statements you can call by name.Stored functions are very similar to procedures, except that a function returns a value to the environment in which it is called.
