NHoldRest
  • NHoldRest is an attribute which specifies that all but the first argument to a function should not be affected by N.
  • See the Mathematica book: Section 2.5.3.

    Further Examples

    Usually N goes inside functions and gets applied to each of their arguments.

    In[1]:=

    Out[1]=

    This tells Mathematica not to apply N to all but the first argument of f.

    In[2]:=

    Now all but the first arguments of f are left in their exact form.

    In[3]:=

    Out[3]=
