In [[number theory]], '''Dirichlet's theorem on Diophantine approximation''', also called '''Dirichlet's approximation theorem''', states that for any [[real numbers]] <math> \alpha </math> and <math> N </math>, with <math> 1 \leq N </math>, there exist integers <math> p </math> and <math> q </math> such that <math> 1 \leq q \leq N </math> and
