In advanced mathematics Algebraic structure Because they are closed under addition, subtraction, and multiplication, but not division, the dyadic rationals are a ring but not a field. The ring of dyadic rationals may be denoted , meaning that it can be generated by evaluating polynomials with integer coefficients, at the argument 1/2. As a ring, the dyadic rationals are a subring of the rational numbers, and an overring of the integers. Algebraically, this ring is the localization of the integers with respect to the set of powers of two.
