1.12 Converting Octal Numbers into Decimal
To convert an octal number into decimal, calculate the sum of the powers of 8 of the number.
Example 1.15
Convert octal number 158 into decimal.
Solution 1.15
Calculating the sum of the powers of 8 of the number:
158 = 1 ? 81 + 5 ? 80
= 8 + 5
= 13
The decimal number is 1310.
Example 1.16
Convert octal number 2378 into decimal.
Solution 1.16
Calculating the sum of the powers of 8 of the number:
