[DLDA]Conversion of decimal to binary using division

[Swapnil]

Conversion of decimal number to binary number system is very easy using division which I often use.

If you want to convert number 27(decimal) to binary,
Then divide the number by 2 repeatedly and keep the track of remainder until the quotient is zero.

If the number is not perfectly divisible then write 1 else 0 where number is perfectly divisible.

27/2 - 13 (rem=1)
13/2 - 6 (rem=1)
6/2 - 3(rem=0)
3/2 - 1(rem=1)
1/2 - 0(rem=1)

The binary number for 27 is 11011.

Hi,

There is programmer mode in Window Calculator which one can use for various conversions.

However it cannot be used in exams as computers are not allowed!
