hierarchical_section_title: Dyadic rational
context_page_description: For any given prime number, a p-adic fraction or p-adic rational is a rational number whose denominator, when the ratio is in minimal terms, is a power of, i.e., a number of the form where a is an integer and b is a natural number. These are precisely the numbers possessing a finite base-p positional numeral system expansion.
  When, they are called dyadic fractions or dyadic rationals; for example, 1/2 or 3/8, but not 1/3.
