Convert 511 from decimal to binary
(base 2) notation:
Power Test
Raise our base of 2 to a power
Start at 0 and increasing by 1 until it is >= 511
20 = 1
21 = 2
22 = 4
23 = 8
24 = 16
25 = 32
26 = 64
27 = 128
28 = 256
29 = 512 <--- Stop: This is greater than 511
Since 512 is greater than 511, we use 1 power less as our starting point which equals 8
Build binary notation
Work backwards from a power of 8
We start with a total sum of 0:
28 = 256
The highest coefficient less than 1 we can multiply this by to stay under 511 is 1
Multiplying this coefficient by our original value, we get: 1 * 256 = 256
Add our new value to our running total, we get:
0 + 256 = 256
This is <= 511, so we assign our outside coefficient of 1 for this digit.
Our new sum becomes 256
Our binary notation is now equal to 1
27 = 128
The highest coefficient less than 1 we can multiply this by to stay under 511 is 1
Multiplying this coefficient by our original value, we get: 1 * 128 = 128
Add our new value to our running total, we get:
256 + 128 = 384
This is <= 511, so we assign our outside coefficient of 1 for this digit.
Our new sum becomes 384
Our binary notation is now equal to 11
26 = 64
The highest coefficient less than 1 we can multiply this by to stay under 511 is 1
Multiplying this coefficient by our original value, we get: 1 * 64 = 64
Add our new value to our running total, we get:
384 + 64 = 448
This is <= 511, so we assign our outside coefficient of 1 for this digit.
Our new sum becomes 448
Our binary notation is now equal to 111
25 = 32
The highest coefficient less than 1 we can multiply this by to stay under 511 is 1
Multiplying this coefficient by our original value, we get: 1 * 32 = 32
Add our new value to our running total, we get:
448 + 32 = 480
This is <= 511, so we assign our outside coefficient of 1 for this digit.
Our new sum becomes 480
Our binary notation is now equal to 1111
24 = 16
The highest coefficient less than 1 we can multiply this by to stay under 511 is 1
Multiplying this coefficient by our original value, we get: 1 * 16 = 16
Add our new value to our running total, we get:
480 + 16 = 496
This is <= 511, so we assign our outside coefficient of 1 for this digit.
Our new sum becomes 496
Our binary notation is now equal to 11111
23 = 8
The highest coefficient less than 1 we can multiply this by to stay under 511 is 1
Multiplying this coefficient by our original value, we get: 1 * 8 = 8
Add our new value to our running total, we get:
496 + 8 = 504
This is <= 511, so we assign our outside coefficient of 1 for this digit.
Our new sum becomes 504
Our binary notation is now equal to 111111
22 = 4
The highest coefficient less than 1 we can multiply this by to stay under 511 is 1
Multiplying this coefficient by our original value, we get: 1 * 4 = 4
Add our new value to our running total, we get:
504 + 4 = 508
This is <= 511, so we assign our outside coefficient of 1 for this digit.
Our new sum becomes 508
Our binary notation is now equal to 1111111
21 = 2
The highest coefficient less than 1 we can multiply this by to stay under 511 is 1
Multiplying this coefficient by our original value, we get: 1 * 2 = 2
Add our new value to our running total, we get:
508 + 2 = 510
This is <= 511, so we assign our outside coefficient of 1 for this digit.
Our new sum becomes 510
Our binary notation is now equal to 11111111
20 = 1
The highest coefficient less than 1 we can multiply this by to stay under 511 is 1
Multiplying this coefficient by our original value, we get: 1 * 1 = 1
Add our new value to our running total, we get:
510 + 1 = 511
This = 511, so we assign our outside coefficient of 1 for this digit.
Our new sum becomes 511
Our binary notation is now equal to 111111111
