On a number line, decimals are a set of numbers that lie between integers. They are simply another way to represent fractions. We can write more precise values of measurable quantities such as length, weight, distance, money, etc using decimals.
The numbers to the left of the decimal point are integers or whole numbers, while the numbers to the right are decimal fractions. In this article, we will learn about decimals.
Decimals Number System
The decimal number system is a positional notation that has a base of 10. It refers to numbers with a fractional part separated from an integer part by a decimal separator. Decimals allow us to write fractions without having to write a fraction with a numerator and denominator.

Decimal Place Value Chart
The position of each digit is important when writing any number. When we go to the right in the below place value chart, the value of the digit becomes 10 times smaller, i.e., one-tenth, and when we move to the left, the value of the digit becomes ten times larger.

Types of Decimals
Decimals are categorised based on the type of digits that follow the decimal point. It depends on whether the digits are non-terminating or terminating.
Non-terminating: 122.353535.... , 3.33333...., 13.66666…
Terminating: 85.9856, 2.5674, 7.5
The decimal numeral system is a standard system for showing integer and non-integer numbers. You can't learn about numbers completely unless you understand decimals. Hopefully, this article has offered you a good understanding of the significance of decimals.
