Subtraction Example

Subtract two binary numbers: 101.1 (5.5 in decimal) and 10.01 (2.25 in decimal).

Align the binary points:

  101.10
 -   10.01 =

Subtract each column, starting from the rightmost bit:

0 (from 101.10) - 1 (from 10.01) requires borrowing:
Borrow from the next column, making it 10 (binary for 2) - 1 = 1 (write down 1)
1 (from 101.10, now 0 after borrowing) - 0 = 0 (write down 0)
The decimal point is aligned
1 (from 101.10) - 0 (from 10.01) = 1 (write down 1)
0 (from 101.10) - 1 (from 10.01) requires borrowing:
Borrow from the next column, making it 10 (binary for 2) - 1 = 1 (write down 1)
- 1 (from 101.10, now 0 after borrowing) - 0 = 0 (write down 0)

Combine the results:

Reading the write down's in reversed order:
011.01

The difference of subtracting  binary numbers 10.01 from 101.1 is 11.01

Convert the binary result to decimal for verification:

11.01` in binary is 3.25 in decimal.
Verify the decimal subtraction:
5.5 - 2.25 = 3.25, confirming the binary result.
