To create numbers, coordinates, or equations using the Input Bar you may also use the following pre-defined functions and operations. Logic operators and functions are listed in article about Boolean values.要利用指令列建立數值、座標或方程式，您可使用下列內建的函數與運算子。與邏輯相關的運算子與函數列表請參閱「真假值」。

備註： 使用內建函數必須使用圓括號而不是方括號，且函數名稱和圓括號之間不可空白。
