What is a decimal number?

A decimal number is a number that is written using the base-10 numbering system. It consists of digits 0 through 9, with each digit's place value determined by its position relative to the decimal point. The decimal point separates the whole number part from the fractional part of the number, allowing for numbers to be expressed in both integer and fractional forms.
