Decimal system

The decimal number system is a number system based on ten. The decimal system is a way of counting and representing numbers using ten digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.

The number is expressed in base-10 where each value is denoted by 0 or first nine positive integers.

The decimal number system is a positional notation system in which each digit in a number represents a power of 10. For example, in the number 538 the first digit represents 5 hundreds , the second digit represents 3 tens, and the third digit represents 8 ones . 538=(5×100)+(3×10)+8
