Convert 236 from decimal to octal
(base 8) notation:
Power Test
Raise our base of 8 to a power
Start at 0 and increasing by 1 until it is >= 236
80 = 1
81 = 8
82 = 64
83 = 512 <--- Stop: This is greater than 236
Since 512 is greater than 236, we use 1 power less as our starting point which equals 2
Build octal notation
Work backwards from a power of 2
We start with a total sum of 0:
82 = 64
The highest coefficient less than 7 we can multiply this by to stay under 236 is 3
Multiplying this coefficient by our original value, we get: 3 * 64 = 192
Add our new value to our running total, we get:
0 + 192 = 192
This is <= 236, so we assign our outside coefficient of 3 for this digit.
Our new sum becomes 192
Our octal notation is now equal to 3
81 = 8
The highest coefficient less than 7 we can multiply this by to stay under 236 is 5
Multiplying this coefficient by our original value, we get: 5 * 8 = 40
Add our new value to our running total, we get:
192 + 40 = 232
This is <= 236, so we assign our outside coefficient of 5 for this digit.
Our new sum becomes 232
Our octal notation is now equal to 35
80 = 1
The highest coefficient less than 7 we can multiply this by to stay under 236 is 4
Multiplying this coefficient by our original value, we get: 4 * 1 = 4
Add our new value to our running total, we get:
232 + 4 = 236
This = 236, so we assign our outside coefficient of 4 for this digit.
Our new sum becomes 236
Our octal notation is now equal to 354
