The standard definition of a binary rational is a rational whose
denominator is a power of 2.

In binary place value notation, they are the infinite strings starting
at the binary point, then having onlybinary digits of 0 or 1, which end
with either a string of infinitely many 0's or infinitely many 1's.

Thus in a Complete Infinite Binary Tree they correspond to infinite
paths with either only finitely many 1's or only finitely many 0's.
