I'm trying to convert from binary number to decimal integer. I have some clues that I have to use predefined function bin2dec() or dec2bin(). Example: 00101101110 --> -657 an example was given by my professor. However, I have no idea how he converted from this binary number to -657. I try to do by hand, converting 00101101110, I got 366. Using bin2dec(), I got 366.

Hi Hoat,

It appears that twos complement or ones complement is involved here although I could not quite get there. Somebody will know.
