	Rational number - Wikipedia, the free encyclopedia
		Each rational number can be written in many forms, for example 3 / 6 = 2 / 4 = 1 / 2.
		For any positive rational number, there are infinitely many different such representations.
		The set of all rational numbers is countable.
	en.wikipedia.org /wiki/Rational_number

	Binary numeral system
		Other rational number s have binary representation, but instead of terminating, they recur, with a finite sequence of digits repeating indefinitely.
		The binary or base-two numeral system is a system for representing numbers in which a radix of two is used; that is, each digit in a binary numeral may have either of two different values.
		The number two is written "10" in binary; the number six requires three digits in binary, "110"; and the number nine-hundred ninety-nine (decimal "999") requires ten digits in binary, "1111100111".

		During the 19th century, many new states were added to the original thirteen as the nation expanded across the North American continent and acquired a number of overseas possessions.
		After long debate, this was supplanted by the Constitution of a more centralized federal government in 1789.
		Two of the major traumatic experiences in the nation's history were the American Civil War ( 1861 - 65) and the Great Depression of the 1930s.

	John Locke
		Such a dyadic relational theory is often called naive realism because it suggests that the perceiver is directly perceiving the object, and naive because this view is open to a variety of serious objections.
		Having set forth the general machinery of how simple and complex ideas of substances, modes, relations and so forth are derived from sensation and reflection Locke also explains how a variety of particular kinds of ideas, such as the ideas of solidity, number, space, time, power, identity, and moral relations arise from sensation and reflection.
		In judging rationally how much to assent to a probable proposition, these are the relevant considerations that the mind should review.

		Otherwise, we could let our \seq $\{x_0,\,x_0,\,x_0,\,\dots,\,x_0,\,\dots\}.$ We will actually construct a \seq of \sla{dyadic} rational numbers $r_n$ that converge to $x_0$ (the dyadic rational n umbers are those whose denominators are powers of $2.$ We may also assume that $x_0>0$ (why?).
		We want to find a \seq of rational numbers that converges to $x_0.$ We may as well assume that $x_0$ is an irrational number.
		We choose as $I_1$ the half of $I_0$ that contains $x_0.$ Both endpoints of $I_1$ are dyadic rationals, since each endpoint is either one of the original endpoints or is $n_0/2.$ \gap We now repeat this process, dividing our chosen intervals in half.

		The number yielded in a finite time is a dyadic rational, but the number yielded (in principle) in the limit as t -> infinity is transcendental with probability 1 if the digits are obtained from thermal noise.

		As an exception, if the exponent is a rational number p/q and x an integer modulo a prime, return a solution y of y^q = x^p if it exists.
		Furthermore note that the result is as exact as possible: in particular, division of two integers always gives a rational number (which may be an integer if the quotient is exact) and not the Euclidean quotient (see x

	An Viable Alternative To Platonism In Math? - Objectivism Online Forum
		For instance, when you construct your number system using something called surreal numbers, you start by creating a particular class of rational numbers (dyadic fractions) which you can then use to define the integers (and later, the real numbers).
		Rational numbers do come after natural numbers in the standard constuction, since they are defined as equivalence classes of ordered pairs of integers, but there are different constructions where this is not true.
		The problem I've always found in the past with attempts to 'construct mathematics rationally' (or whatever) is that they tend to be exercises in psychologism, largely focusing on how humans acquire knowledge of mathematical concepts.

	Elementary Mathematics in J
		Extended integer and rational are atomic data types (like numeric, literal, and boxed) that allow representation of numbers with arbitrary accuracy.
		The integer was made into a rational number so it keeps its precision.
		An extended integer constant is defined by a sequence of digits with the letter x appended; a rational constant is two strings of digits (numerator and denominator) separated by the letter r; examples are 123x and 4r5.

		Infinite sets of points with rational distances are known, from which arbitrarily large finite sets of points with integer distances can be constructed; however it is open whether there are even seven points at integer distances in general position (no three in a line and no four on a circle).

	Origins of Randomness in Physical Systems
		But if the initial condition is ``simple,'' say a rational number with a periodic digit sequence, then no randomness appears.
		For systems such as iterated mappings of the interval there seems to be no robust notion of ``simple'' initial conditions.
		There are, however, systems which can also generate apparent randomness internally, without external random input.

		What this paper does is to analyse various characteristics of continued fraction expansion of rational numbers.
		The algorithm can be viewed as a race between a "dyadic" hare with a speed of 2 bits by step and a "real" tortoise with a speed equal to about 0.05 bits by step.
		Here, we prove that the average case number of steps is asymptotically constant and that the probability of executing a large number of reduction steps decays exponentially.

	Encyclopedia: Rational number
		In mathematics, a dyadic fraction or dyadic rational is a rational number that when written as a fraction has denominator a power of two, i.
		In mathematics, a rational number (or informally fraction) is a ratio or quotient of two integers, usually written as the vulgar fraction a/b, where b is not zero.
		The decimal expansion of a rational number is eventually periodic (in the case of a finite expansion the zeroes which implicitly follow it form the periodic part).
