Format

Format[expr]
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.
