## Operator

,/* top */Spelling, grammar, and general fixes

An '''operator''' is a ~~map ~~[[mapping]] from [[function space ]] to function space. If the [[range ]] of ~~an ~~the operator is on the [[real line]] or in the [[complex plane]], the operator is usually called a [[~~function~~functional]]~~al ~~instead. The most commonly used operators in mathematics are [[binary operator]]s.

An '''operator''' is also a person who makes [[phone ]] connections, though this practice is becoming less common as the process becomes more automated.

More generally, an '''operator''' can refer to anyone who operates heavy or complicated [[machinery]]. Examples: [[forklift]] operator, [[radar]] operator, [[system]] operator ([[sysop]]).
