2.2 Decimal-To-Binary Conversion
There are 2 methods:
(A) Reverse of Binary-To-Digital Method
|
45 10 |
= 32 + 0 + 8 + 4 +0 + 1 |
|
|
= 25+0+23+22+0+20 |
|
|
= 1 0 1 1 0 12 |
(B) Repeat Division
This method uses
repeated division by 2. Eg. convert 2510 to binary
|
25/ 2 |
= 12+ remainder of 1 |
1 (Least Significant Bit) |
|
12/ 2 |
= 6 + remainder of 0 |
0 |
|
6 / 2 |
= 3 + remainder of 0 |
0 |
|
3 / 2 |
= 1 + remainder of 1 |
1 |
|
1 / 2 |
= 0 + remainder of 1 |
1 (Most Significant Bit) |
|
Result |
2510 = |
1 1 0 0 12 |
