FullForm

  • FullForm[ expr ] prints as the full form of expr, with no special syntax.
  • Example: FullForm[a + b^2].
  • FullForm acts as a "wrapper", which affects printing, but not evaluation.
  • See the Mathematica book: Section 2.1.1, Section 2.1.1, Section 2.1.4, Section 2.3.1, Section 2.3.13Section 2.8.1.
  • See also: InputForm, TreeForm.

    Further Examples

    Here is the FullForm of a polynomial.

    In[1]:=

    Out[1]//FullForm=

    This gives the FullForm of an equation.

    In[2]:=

    Out[2]//FullForm=
