Numbers Every number system is associated with a base or radix A positional notation is commonly used to express numbers (a5 a4 a3a2 a1a0 ) r  a5 r 5  a4 r 4  a3r 3  a2 r 2  a1r1  a0 r 0 The decimal system has a base of 10 and uses symbols (0,1,2,3,4,5,6,7,8,9) to represent numbers (2009)10  2 103  0 102  0 101  9 100 (123.24)10  1102  2 101  3 100  2 10 1  4 10 2 An octal number system has a base 8 and uses symbols (0,1,2,3,4,5,6,7) (2007)8  2  83  0  82  0  81  7  80 What decimal number does it represent? 1031 Electronics - I, The LNM Institute of Information Technology, Jaipur 3
A hexadecimal system has a base of 16 Number Symbol 0 0 1 1 2 2 3 3 4 4 5 5 6 6 7 7 8 8 9 9 10 A 11 B 12 C 13 D 14 E 15 F (2BC9)16 =2 ∗ 163 + 𝐵 ∗ 162 + 𝐶 ∗ 161 + 9 ∗ 160 How do we convert it into decimal number? (2BC9)16 =2 ∗ 163 + 11 ∗ 162 + 12 ∗ 161 + 9 ∗ 160 = 11209 Electronics - I, The LNM Institute of Information Technology, Jaipur 4
