The Octave online help is your friend:

 - Function File:  num2str (X)
     Convert a number to a string.  These functions are not very
     flexible, but are provided for compatibility with MATLAB.  For
     better control over the results, use `sprintf' (*note Formatted
     Output::.).

Since it's a function file, you can look at the code, which in my version
of Octave says:

 retval = sprintf ("%g", x);

so whatever controls the %g formatting controls the num2str formatting.
There's probably a global variable to control the cutover from fixed point
to exponential format.  I don't recall it offhand, so I'll leave it to you
to find it in the help.

HTH,

Steven
