-Some functions are overloaded and thus they may return values of miscellaneous types. When calling a function, you must explicitly specify which type you wish to call by appending the right [[https://en.wikipedia.org/wiki/Sigil_(computer_programming)|sigil]] to the function name. For example, the [[ABS|ABS function]] can return an integer or a float:+Some of the built-in functions are overloaded and thus they may return values of miscellaneous types.
