Hi,

could anyone tell me how to convert decimal 3 200 000 to binary ? I can convert smaller decimal number to binary using the binary positions like   128 64 32 8 4 1 2 ...... but how could I convert decimal 3 200 000 to binary without writing the long binary position until that number? is there a way to calculate it? Thanks.

There is a way to convert decimal to binary without using a calculator or computer.

 

3200000 / 2 = 1600000....0

1600000 / 2 = 800000....0

800000 / 2 = 400000....0

400000 / 2 = 200000....0

200000 / 2 = 100000....0

100000 / 2 = 50000....0

50000 / 2 = 25000....0

25000 / 2 =12500....0

12500 / 2 = 6250....0

6250 / 2 = 3125....0

3125 / 2 = 1562....1

1562 / 2 = 781....0

781 / 2 = 390....1

390 / 2 = 195....0

195 / 2 = 97....1

97 / 2 = 48....1

48 / 2 = 24....0

24 / 2 = 12....0

12 / 2 = 6....0

6 / 2 =3....0

3 / 2 =1....1

1 / 2 =0....1

 

Look at the remainder after you divide, then read the remainders from the last to the first, you get:

1100001101010000000000 -> this is the answer

 

This is what I know, maybe there is a easier way, you can search the web for help.

The easiest way is to use online calculator to help you calculate, like opera said. If you want to calculate it by hand I only know this method, you can search the internet for an easier way.

There is a perfectly good calculator built into Windows. chose 'Programmer view' and you can convert numbers to your heart's content between decimal, binary, hex and even octal.

 

Batman is cleverer than I am - I was probably exposed to his method once upon a time but promptly forgot it. But his answer is exactly the same as the one the Windows calculator just produced, so the calculator must be right.

I am going to be away until about the 22nd October. Time on-line will be reduced and my internet access may be limited. PMs may not be replied to as quickly as normal !
