All whole numbers **are integers**, so since 0 is a whole number, 0 is also an integer.

Therefore, 2. **56 is a Rational number**.

**All whole numbers are integers** (and all natural numbers are integers), but not all integers are whole numbers or natural numbers. For example, -5 is an integer but not a whole number or a natural number.

The **empty set is nowhere dense**. In a discrete space, the empty set is the only such subset. In a T_{1} space, any singleton set that is not an isolated point is nowhere dense. The boundary of every open set and of every closed set is nowhere dense.

The integers, for example, **are not dense in the reals** because one can find two reals with no integers between them. That definition works well when the set is linearly ordered, but one may also say that the set of rational points, i.e. points with rational coordinates, in the plane is dense in the plane.

Thus, R α R_{alpha} Rα is dense in **[ 0 , 1 ] [0,1]** [0,1].

Let x∈Q. Let U⊆R be an open set of (Q,τd) such that x∈U. From Basis for Euclidean Topology on Real Number Line, the set of all open real intervals of R form a basis for (R,τd). … Hence **(Q,τd) is dense-in-itself**.

Informally, for every point in X, the point is either in A or arbitrarily “close” to a member of A — for instance, the rational numbers are a dense subset of the real numbers **because every real number either is a rational number or has a rational number arbitrarily close to it** (see Diophantine approximation).

The real algebraic numbers are **dense in the reals**, linearly ordered, and without first or last element (and therefore order-isomorphic to the set of rational numbers).

Definition 78 (Dense) A subset S of R is said to be dense in R **if between any two real numbers there exists an element of S**. Another way to think of this is that S is dense in R if for any real numbers a and b such that a

If nx≠1−k, you’re done: just take m=1−k. If nx=1−k, take m=2−k. If Q is not dense in R, then there are two members x,**y∈R** such that no member of Q is between them.

To the right are all positive numbers, and to the left are the negative points. … Therefore, all of these **rational and irrational numbers**, including fractions, are considered real numbers. Real numbers that include decimal points are known as floating point numbers because the decimal floats within the numbers.

**Rational numbers** (Q). This is all the fractions where the top and bottom numbers are integers; e.g., 1/2, 3/4, 7/2, ⁻4/3, 4/1 [Note: The denominator cannot be 0, but the numerator can be].

The integers are the set of whole numbers and their opposites. **Fractions and decimals are not included in the set of integers**. For example, 2,5,0,−12,244,−15 and 8 are all integers.

**Pi is an irrational number**, which means that it is a real number that cannot be expressed by a simple fraction. … When starting off in math, students are introduced to pi as a value of 3.14 or 3.14159.

In number theory, natural density (also referred to as asymptotic density or arithmetic density) is **one method to measure how “large” a subset of the set of natural numbers is**. … If this probability tends to some limit as n tends to infinity, then this limit is referred to as the asymptotic density of A.

The number density (symbol: n or ρ_{N}) is **an intensive quantity used to describe the degree of concentration of countable objects** (particles, molecules, phonons, cells, galaxies, etc.) … Population density is an example of areal number density.

The formula for density is **d = M/V**, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.

The fraction **2/3** is a rational number.

0.64 is **a rational number**.

No matter how big your circle, the ratio of circumference to diameter is the value of Pi. Pi is **an irrational number—**you can’t write it down as a non-infinite decimal.

If the number is in decimal form then it is **rational** if the same digit or block of digits repeats. For example 0.33333… is rational as is 23.456565656… and 34.123123123… and 23.40000… If the digits do not repeat then the number is irrational.

An integer (pronounced IN-tuh-jer) is a whole number (not a fractional number) that can be positive, negative, or zero. Examples of integers are: -5, 1, 5, 8, 97, and 3,043. Examples of numbers that are not integers are: **-1.43, 1 3/4, 3.14, .** **09**, and 5,643.1.
