Convert 87 from decimal to hexadecimal
(base 16) notation:
Raise our base of 16 to a power
Start at 0 and increasing by 1 until it is >= 87
160 = 1
161 = 16
162 = 256 <--- Stop: This is greater than 87
Since 256 is greater than 87, we use 1 power less as our starting point which equals 1
Work backwards from a power of 1
We start with a total sum of 0:
The highest coefficient less than 15 we can multiply this by to stay under 87 is 5
Multiplying this coefficient by our original value, we get: 5 * 16 = 80
Add our new value to our running total, we get:
0 + 80 = 80
This is <= 87, so we assign our outside coefficient of 5 for this digit.
Our new sum becomes 80
Our hexadecimal notation is now equal to 5
The highest coefficient less than 15 we can multiply this by to stay under 87 is 7
Multiplying this coefficient by our original value, we get: 7 * 1 = 7
Add our new value to our running total, we get:
80 + 7 = 87
This = 87, so we assign our outside coefficient of 7 for this digit.
Our new sum becomes 87
Our hexadecimal notation is now equal to 57
