OCTAL BASE 8 MATH (RADIX = 8)

(Home)

SCALE:   OCTAL RANGE = (0 to 7)

Question:

Add 75 + 8

Answer:

How many columns will I need?

Log(What ever number that you are trying to scale) / Log(radix)

Log of 75 /Log of 8(radix) = 2.07

Always round up if there is a remainder.

We will need 3 columns!

EACH col represents 3 bits

2bits + 3 bits + 3 bits

COLUMNS       64-8-1

BIT VALUE       1  1  3

BIT VALUE       0  1  0

TOTAL              1  2  3
