rational

[Mathematics] a fractional number n/d, where n and d are integers, n is the numerator and d is the denominator. The set of all rational numbers is usually called Q. Computers do not usually deal with rational numbers but instead convert them to real numbers which are represented (approximately in some cases) as floating-point numbers. Compare irrational.

In this section we study the neutrosophic duplets of the neutrosophic rings <Q [union] I> = {a+bI|a, b [member of] Q, [I.sup.2] = I}; where Q the field of rationals and <R [union] I> = {a + bI|a, b, [member of] R, [I.sup.2] = I}; where R is the field of reals.
Because 5/3 CDF filter coefficients are dyadic rational values and so the integer to integer transform is obtained by using this feature [38].
The symbols N, Q, and R denote the sets of positive integers, rational and real numbers, respectively.
Along the way we will introduce a lagrangian that exists as a purely polynomial expression and removes the need for complicated nonanalytic measures and rational inverse matrix functions.
In general, though, discrete non-positive measures on R do not attain their norm; for instance, let [[q.sub.n]] be an enumeration of the rationals and let [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII]; since Q is everywhere dense in R, there is no continuous function f such that f([q.sub.n]) = [(-1).sup.n], and so [mu] cannot attain its norm as a functional on C(R).
Topics follow the order of whole numbers, fractions, integers, rationals, and reals.
(71.) Although all real numbers can be defined as limits of infinite sequences of rationals, almost all of these numbers are noncomputable in the sense that they cannot be computed via any possible algorithm.

Note that it is known that the boundary complex of a simplicial polytope has the WLP over the rationals.
