To convert a decimal number to binary, you simply need to divide by 2 and take note of the remainder.
Example:
23 / 2 = 11 Remainder 1
11 / 2 = 5 Remainder 1
5 / 2 = 2 Remainder 1
2 / 2 = 1 Remainder 0
2 / 1 = 0 Remainder 1
The answer is therefore 10111.
NB: If the question is to answer is 8-bit you must pad it out with zeroes as follows:
00010111
Decimal 23 is 10111 in binary
To convert a binary number to Excess-3 code, first, convert the binary number to its decimal equivalent. Then, add 3 to the decimal value. Finally, convert the resulting decimal number back to binary. For instance, to convert the binary number 1010 (which is 10 in decimal), you would calculate 10 + 3 = 13, and then convert 13 back to binary, resulting in 1101 in Excess-3 code.
The binary number 11.1 in decimal would be 3.5
Binary 110111 is equivalent to decimal 55.
