Question

positional values of 1. 7 in 475.12 at base 8

Answer 1

Answer:

Octal Number System is one the type of Number Representation techniques, in which there value of base is 8. That means there are only 8 symbols or possible digit values, there are 0, 1, 2, 3, 4, 5, 6, 7. It requires only 3 bits to represent value of any digit. Octal numbers are indicated by the addition of either an 0o prefix or an 8 suffix.

Position of every digit has a weight which is a power of 8. Each position in the Octal system is 8 times more significant than the previous position, that means numeric value of an octal number is determined by multiplying each digit of the number by the value of the position in which the digit appears and then adding the products. So, it is also a positional (or weighted) number system.

Representation of Octal Number

Each Octal number can be represented using only 3 bits, with each group of bits having a distich values between 000 (for 0) and 111 (for 7 = 4+2+1). The equivalent binary number of Octal number are as given below −
