Tagastusparameetrid, also known as return parameters, are values that a function or method sends back to the code that called it. When a function performs a task, it often needs to communicate the result of that task to the calling program. This communication is achieved through return parameters.

In programming, a function can be designed to either perform an action or to compute and return a value. Functions that return values use return parameters to specify what kind of data will be sent back. For instance, a function designed to calculate the sum of two numbers would have return parameters that specify it will return an integer or a floating-point number representing the sum.

The mechanism for returning values varies across programming languages. Some languages use a specific return statement (e.g., `return` in Python, Java, C++), while others might employ output parameters or return multiple values through different means. Understanding how a function returns its results is crucial for correctly integrating it into a larger program, ensuring that the returned data is captured and used as intended. Without return parameters, functions would be limited to performing actions without providing any quantifiable output.
