# Is Champernowne constant rational?

## Is Champernowne constant rational?

The simple continued fraction expansion of Champernowne’s constant has been studied as well. Kurt Mahler showed that the constant is transcendental; therefore its continued fraction does not terminate (because it is not rational) and is aperiodic (because it is not an irreducible quadratic).

What is an example of continued fraction?

Examples of continued fraction representations of irrational numbers are: √19 = [4;2,1,3,1,2,8,2,1,3,1,2,8,…] (sequence A010124 in the OEIS). The pattern repeats indefinitely with a period of 6.

### What are continued fractions used for?

Additionally, continued fractions are used in computer algorithms for computing rational number approximations to real numbers, and as we discover in Chapter 3, can be used to solve equations for which there is more than one solution.

### Are irrational numbers computable?

However, the set of all irrational numbers is uncountable, so there must be some irrational number whose decimal expansion is not computable! In fact, since only countably many irrational numbers can be computed, “most” irrational numbers are not computable!

Is Pi a normal number?

Irrationality. In the 18th century, the Swiss mathematician Johann Lambert proved that π is an irrational number. This means that it is impossible to express π as a fraction of two integers. As a consequence, π has an infinite number of digits and does not end in an infinitely repeating pattern of digits.

#### What is 2453 continued fraction?

Expert-verified answer √2453 = 49 + 52 / ( 49 + 52 / ( 49 + 52/49 + ………………)

#### What is meant by continued fraction?

Definition of continued fraction : a fraction whose numerator is an integer and whose denominator is an integer plus a fraction whose numerator is an integer and whose denominator is an integer plus a fraction and so on.

Are all integers computable?

No, there is not. If you consider an integer with the usual meaning, it is finite information. All finite information can be computed. For example, you can build a machine M and the proposition “M halts on input 0” can be impossible to prove in any known usual theory.
