Just curious how that is coming about.

It is curious.  The code (in libinterp/corefcn/mappers.cc) seems to
read as it will return an integer which is what the C++ signbit function does. 
However:
octave:1> sbit = signbit(-1.2)
sbit =  1
octave:2> whos
Variables in the current scope:

   Attr Name        Size                     Bytes  Class
   ==== ====        ====                     =====  =====
        sbit        1x1                          8  double

So, I am missing something.
