StandardForm
StandardForm[expr]
prints as the standard Wolfram Language two-dimensional representation of expr.
Details
- StandardForm generates output that gives a unique and unambiguous representation of Wolfram Language expressions, suitable for use as input. »
- StandardForm incorporates many aspects of traditional mathematical notation.
- StandardForm is the standard format type used for both input and output of Wolfram Language expressions in notebooks.
- Graphics and Graphics3D are displayed graphically in StandardForm.
- StandardForm can be edited in the notebook front end.
- StandardForm uses special characters as well as ordinary keyboard characters.
- StandardForm is based on boxes.
- The notebook front end contains menu items for conversion to and from StandardForm.
- When an input evaluates to StandardForm[expr], StandardForm does not appear in the output. »

When an input evaluates to StandardForm[expr], StandardForm does not appear in the output:
Out is assigned the value x2, not StandardForm[x^2]:
StandardForm is two-dimensional unambiguous formatting:
OutputForm approximates StandardForm using keyboard characters:
TraditionalForm is two-dimensional, but ambiguous formatting:
InputForm and FullForm provide one-dimensional formatting:
Use ToString to generate a string in StandardForm:
The string includes two-dimensional markup:
Use ToExpression to convert back:
Use ToBoxes to get the box representation of an expression in StandardForm:
Use ToExpression to convert back:
Add formatting via Format:
Possible Issues (1)
Even when an output omits StandardForm from the top level, it is not stripped from subexpressions:
The output does not have StandardForm in it:
However, the variable e does have StandardForm in it, which may affect subsequent evaluations:
The product is not evaluated due to the intervening StandardForm:
Assign variables first and then apply StandardForm to the result to maintain computability:
