prints as the formatted form of expr. Assigning values to Format[expr] defines print forms for expressions.

Format[expr, form]
gives a format for the specified form of output.


  • Standard forms for formatted output are:
  • CFormC language input form
    FortranFormFortran input form
    InputFormone-dimensional form suitable for direct keyboard input
    MathMLFormMathML form
    OutputFormcharacter-based two-dimensional form
    StandardFormstandard two-dimensional form
    TeXFormTeX input form
    TraditionalFormform approximating traditional mathematical notation
  • You can add your own forms for formatted output.
  • Format[s]:=rhs defines a symbol s to print like rhs.
  • Format[f[...]]:=rhs defines a function f to print like rhs.
  • If you specify a new output format for an expression by giving a definition for Format, there is no guarantee that Mathematica will be able to interpret this output format if it is used as input.
  • Definitions given for Format are used before those given for MakeBoxes.
