- To convert a number into binary form:
- First , divide the number by two
- Next, record the remainder (this will wither be zero or one)
- Next, repeat this process until the quotient is equal to zero
- Finally, display the remainders in reverse order to convert your number into binary form!
- Example:
- Binary number for 4:
- 4/2 = 2 (remainder zero)
- 2/2 = 1 (remainder zero)
- 1/2 = 0.5 (remainder one)
- To convert a binary number into numerical form:
- Multiply each digit of a binary number from right to left with powers of 2 starting from 0 and add each result to get the number value
- Example:
- Number value for 10101:
- 1 x 2^0 = 1
- 0 x 2^1 = 0
- 1 x 2^2 = 4
- 0 x 2^3 = 0
- 1 x 2^4 = 16
