InputForm

  • InputForm[ expr ] prints as a version of expr suitable for input to Mathematica.
  • Example: InputForm[x^2 + 1/a].
  • InputForm always produces one-dimensional output, suitable to be typed as lines of Mathematica input.
  • InputForm acts as a "wrapper", which affects printing, but not evaluation.
  • Put (>>) produces InputForm by default.
  • Short[InputForm[ expr ]] can be used, but may generate skeleton objects which cannot be given as Mathematica input.
  • The option NumberMarks can be used to specify whether ` marks should be used to indicate type, precision or accuracy of approximate numbers.
  • See the Mathematica book: Section 1.9.4, Section 1.10.9Section 2.8.1.
  • See also: OutputForm, FullForm, StandardForm.

    Further Examples

    Here is a Mathematica expression; both input and output are in StandardForm.

    In[1]:=

    Out[1]=

    This gives the InputForm.

    In[2]:=

    Out[2]//InputForm=
