To Convert any decimal number into binary
we can folow these steps
Lets Do it With An Exammple
decimal 22 into binary
make a table like this
1
2
4
8
16
32
64
..
..
..
if u wanna convert 22 look for the number or the number just smaller than this,so what i see that the table does not have 22 so the number next smaller than this is 16,write 1 in front of it
1
2
4
8
16--1
32
64
..
..
..
ok next step reduce 16 from the number 22,22-16=6
now we get the number 6 repeat the same procedure,we do not have 6 in the table but do have 4, write 1 in front of it
1
2
4 --1
8
16--1
32
64
..
..
..
now the repeat the same deduct 4 out of 6 ,6-4=2 you got 2 which is in the table,write 1 in front of it
1
2 --1
4 --1
8
16--1
32
64
..
..
..
now when u deduct you 0,2-2=0 so ur binary is complete
now to the remaining table numbers put a 0 in front of it
1 --0
2 --1
4 --1
8 --0
16--1
32
64
..
..
..
now just read the number from down to up,10110 here is your binary conversion
hope you understand this easily
