On the TI-Nspire calculator, every division answer given, unless irrational, is given in exact form, either as an integer or as a fraction. I can do this in Perl with the fraction module. Every square root answer given is also given in exact form, either as an integer or as a radical. I do not know how to do this in perl. How do you convert a number to a radical?

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
