How to convert 0x88 int obinary can any one explain please ?

@Swathi:
to conevrt hex to binary u need to take each digit of hex value and write its binary equivalent.
For eg:-
if hex = 88 , its binary would be
bin = 1000 1000
since binary equivalent of 8(decimal) is 1000.

example2:-
if hex = AF , its binary equi is
bin = 1010 1111
as binary equi of 'A'(in decimal system its 10) 1010 and that of 'F'(in decimal its 15) is 1111

Hope this will help u.
Take care :)

How would you convert binary into decimal (0000 0001 0000 0000=256) ?

@nikita.

Bitwise operator can't be applied to float and double type. This its limitation,

Check out in books.
