StandardForm[expr]
prints as the standard Wolfram Language two-dimensional representation ofexpr.
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 andGraphics3D are displayed graphically inStandardForm.
- 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 fromStandardForm.
- When an input evaluates toStandardForm[expr],StandardForm does not appear in the output.»

When an input evaluates toStandardForm[expr],StandardForm does not appear in the output:
Out is assigned the valuex2, notStandardForm[x^2]:
StandardForm is two-dimensional unambiguous formatting:
OutputForm approximatesStandardForm using keyboard characters:
TraditionalForm is two-dimensional, but ambiguous formatting:
InputForm andFullForm provide one-dimensional formatting:
UseToString to generate a string inStandardForm:
The string includes two-dimensional markup:
UseToExpression to convert back:
UseToBoxes to get the box representation of an expression inStandardForm:
UseToExpression to convert back:
Add formatting viaFormat:
Possible Issues (1)
Even when an output omitsStandardForm from the top level, it is not stripped from subexpressions:
The output does not haveStandardForm in it:
However, the variablee does haveStandardForm in it, which may affect subsequent evaluations:
The product is not evaluated due to the interveningStandardForm:
Assign variables first and then applyStandardForm to the result to maintain computability:
