is a low-level box construct which displays as boxes but specifies that rules associated with form should be used to interpret boxes on input. }})

OpenersNotesSection(Spacer1)Details

In (RefLink[InputForm, paclet:ref/InputForm]) and (RefLink[StandardForm, paclet:ref/StandardForm]), \(form∖`input∖) yields (RefLink[FormBox, paclet:ref/FormBox])[input,form].

∖(∖`input∖) yields (RefLink[FormBox, paclet:ref/FormBox])[input,RawForm].

Create a cell with (RefLink[TraditionalForm, paclet:ref/TraditionalForm]) style settings applied:

CellPrint[Cell[BoxData[FormBox[RowBox[{"sin","(","x",")"}],TraditionalForm]],"Output"]]

Create a cell with (RefLink[StandardForm, paclet:ref/StandardForm]) style settings applied:

CellPrint[Cell[BoxData[FormBox[RowBox[{"sin","(","x",")"}],StandardForm]],"Output"]]

(RefLink[FormBox, paclet:ref/FormBox]) affects interpretation of its contents:

Table[ToExpression[FormBox[RowBox[{"f","(","x",")"}],fm]],{fm,{TraditionalForm,StandardForm}}]

FullForm/@%

(RefLink[TraditionalForm, paclet:ref/TraditionalForm]) formatting uses (RefLink[FormBox, paclet:ref/FormBox]):

ToBoxes[x/Sqrt[1-x^2],TraditionalForm]//FullForm

The formatted result looks like this:

x/Sqrt[1-x^2]//TraditionalForm
