Hi, The difference between the two ( perfectly possible ) interpretations lie in if the number is signed or positive. If it's signed then the most significant bit is considered to be negative and with 8 data bits (one byte )we would get a range from - 128 to + 127. If the number is unsigned then the the range is ...

3 bit value is---->11 for finding -3 value(flip+add 1) fliping gives----->1111 1111 1111 1111 1111 1111 1111 1111 1100 add 1 gives----> 1111 1111 1111 1111 1111 1111 1111 1111 1101(this is the result of -3 bit representation) But when i convert the previous bit representation back to decimal as 1*2^0+0*2^1+1*2^2--->-5 (why it is not giving -3 value) Then how come ...

What do you mean by a 'binary integer'? Java has an Integer class, and an int primitive. How the values are stored is not relevant to how they are displayed. So let's back up a little. What exactly do you have, and what exactly do you need to do? Can you provide some code samples to show us?

mTeigeler, I've just replied to three threads you also replied to and each time you posted a "solution" that only vaguely resembles something that might be related to the OPs actual question. What's with the byte array and the BigInteger? The OP has stated he has a String representing a 10 digit binary number...

Stopper is quite correct. You are missing the things Stopper noted. To trouble shoot such code use your compiler output or a decent IDE like Eclipse or JBuilder which will auto compile and highlight your errors quickly. You can clean up your method code by adding the variable defnition and initialization code mentioned at the beginning of the method.

You don't actually look at c. You grab it, then ignore it. All you have to do is start using it. You could parse the character into a number, but since it's a single digit that's either 1 or 0, you could just as easily use an if/else statement. If it's 1, then take the exponent as you are. If it's ...
