Hi , I only recently read the construction of reals from rationals.(adsbygoogle = window.adsbygoogle || []).push({});

I could grasp that [itex]\sqrt{2}[/itex] can be represented as the set of rationals given by

{x[itex]\in[/itex] Q : x^{2}< 2 } . As we know this set is defined purely in terms of Q.

Is there a dedekind cut representation for pi as well ?

I read somehwhere that not all reals can be defined. But since pi is defined , what would it's dedeking cut representation be?
