In simple settings, the [[return type|resulting value]] is usually one of various [[primitive data type|primitive types]], such as numerical, [[string (computer science)|string]], and [[boolean expression|logical]]; in more elaborate settings, it can be an arbitrary [[complex data type]]. In [[functional programming]], the resulting values are often functions or expressions, which can themselves be further evaluated.

For example, <code>2+3</code> is an arithmetic and programming expression which evaluates to <code>5</code>. A variable is an expression because it denotes a value in memory, so <code>y+6</code> is an expression. An example of a relational expression is <code>4≠4</code>, which evaluates to <code>false</code>.<ref>[https://developer.mozilla.org/en/Core_JavaScript_1.5_Guide/Expressions Javascript expressions, Mozilla] Accessed July 6, 2009</ref><ref>[https://www.cs.drexel.edu/~rweaver/COURSES/ISTC-2/TOPICS/expr.html Programming in C] Accessed July 6, 2009</ref>
