Conversion from long/long double to binary

[mystiq]

How can I convert numbers input as long/long double data type to binary in C/C++???

The program is in 2 parts. First teh program has to change inputs from long(32 bits) to binary and then show the result. Secondly change input from long double(80 bits??) to binary. The codes should be preferably in C++ but maybe in C too its ok.

not sure what you want do do - when data is read into the computer e.g. using scanf() in C or cin in C++, it is converted into the internal binary representation, see

do you want to print a double in binary, e.g. integer 5 as a 8 bit binary number is 00000101?

Yeah I want to print a long/long double in binary. for instance. I input a number 2,115,000,000 (long data type). How can I convert it to binary?
