A function that processes a set of inputs and results in a set of outputs, or associates arguments (inputs) with values (outputs).|Special cases are: a) An operation that consumes no input (has no input arguments). Such operation is either a constant function, or an operation depending only on the underlying state. b) An operation that may modify the underlying state but has no output. c) The singular-case operation with no input or output, that still may modify the underlying state.
