DECIMAL NUMBER SYSTEM

In our daily life, we use decimal number system. Decimal number system has ten digits that represent 0,1,2,3,4,5,6,7,8, and 9. In the decimal number system, the base (radix) is 10, because there are altogether ten digits (or symbols). As we know, in this system, decimal point represents units, tens, hundreds, thousands, from left etc. However, each position of digits refers a specific power of the radix (or base) 10.

For instance, Decimal number 2468 consist of digit 8 in unit positions. Thus, we can write to the value of 2468 as follows: 2x10**3+4x10**2+6x10**1+8x10**0
=2000+400+60+8
=2468i.e.(2468)10
