Infinite Cycle Decimal: Starting from a certain digit after the decimal point, the decimal number is displayed repeatedly. Such as 2. 1666…, 35.23 …, and so on. A repeated number or segment is called a cyclic segment.

Infinitely cyclic decimals: Some decimals are infinite, but not cyclic. Irrational numbers are not like circular decimals. Every number is repeated, but it is also an infinite decimal.

The decimal part of the pure cyclic decimal of the extended data can be written as follows: What is the minimum number of digits in the cyclic segment of the pure cyclic decimal, and the denominator is a number consisting of several 9s; A molecule is a number consisting of a cyclic node in a pure cyclic decimal system. ?

Mathematically, infinite acyclic decimals are also called irrational numbers (for example, pi is irrational numbers), and all other real numbers are called rational numbers. (π reads pài)?

Types of irrational numbers

1, the prescription is inexhaustible (such as root number 2)

2, related to π (such as π+2)?

3. Regular but not cyclic (e.g. 0.1010010001)?

Pure cyclic decimal refers to the cycle starting from the first digit, which is called pure cyclic decimal.

Mixed cycle decimal refers to the cycle starting from the second digit, which is called mixed cycle decimal.
