Fiction books in libraries are typically assigned Dewey Decimal Classification numbers in the 800s, specifically in the 813-819 range for American literature and its subdivisions. However, many libraries use different classification systems for fiction, such as the Library of Congress Classification system, which assigns fiction books a combination of letters and numbers based on author names and subjects. In general, while Dewey Decimal numbers can be used for fiction books, they are not a strict requirement and may vary depending on the library's cataloging practices.
All real numbers can be represented in the decimal system. Complex numbers can be represented by a pair of numbers in the decimal system.
The decimal representation of numbers is shorter. Binary number require approx 3.3 times as many digits.

The decimal system was and still is based on representing numbers in such a way that the place value of each digit is ten times that of the digit to its right. If it does not contain a fractional part then the decimal representation does not require a decimal point.
Fiction books are usually placed outside the Dewey system in public libraries (which use Dewey most often) but can be placed in 813 (American Fiction) and/or 823 (British fiction). Fiction of other languages follows the same protocol-- Spanish fiction in 863, for example.
The library uses the Dewey Decimal Classification system to allocate numbers to books.
The two general kinds of book classifications in a library are the Dewey Decimal Classification system and the Library of Congress Classification system. The Dewey Decimal system categorizes books by subject based on a numerical system, while the Library of Congress system organizes books by both subject and author through a combination of letters and numbers.
The system used most extensively is the Dewey Decimal Classification or DDC, also called the Dewey Decimal System. It was developed, in its original form by Melvil Dewey in the mid 1870's Scitech
Books in the library are generally classified using the Dewey Decimal Classification system or the Library of Congress Classification system. The Dewey Decimal Classification system categorizes books based on subjects into 10 main classes. The Library of Congress Classification system organizes books by more specific topics using a combination of letters and numbers.

The Decimal System
The Base-10 number system is known as the decimal system and has 10 digits to show all numbers 0,1,2,3,4,5,6,7,8,9 using place value and a decimal point to separate whole numbers from decimal fractions.
