Based on 10
The numbers we use in everyday life are decimal numbers, as they are based on the 10 digits {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
"Decimal number" is often used to mean a number that uses a decimal point followed by digits that show a value smaller than one.
Example: 45.6 (forty-five point six) is a decimal number.
