Definition of Decimal
A decimal is a base-10 number. The numbers we use every day are decimal numbers. They are based on the 10 digits \(\{0,1,2,3,4,5,6,7,8,9\}\).
We probably use a decimal number system because the average human has 10 fingers to count on.
The term, "decimal number" is often used to refer to a number which includes a decimal point, followed by digits that represent multiples of values like \(\dfrac{1}{10}\) and \(\dfrac{1}{100}\) that are less than one.
For example, \(256.32\) is a decimal number.
