Easy to use
How is the sign of the number represented ?
The first number of the word is sign
The first bit of the word is reserved for the sign of the number.
The magnitude of the number
The last (least significant) bit.
Octal numbers are used
In compute hardware
When binary numbers are too long
External to the computer
In preference to next numbers
Suppose 28 is a number in base 9 system. Convert this number to base 8 number
