GNU Octave: How to change base from DEC to BIN?

"The long answer is, it's possible, but you'll have to a) program it yourself, or b) get someone to program it for you. This method of writing fractional base-2 just isn't used in computing.

Programming a function to convert this representation of fractional binary numbers into standard IEEE754 double-precision floating point binary isn't impossible, so if it's an absolute must-have, it is doable."
