  ** The parser has been extended to understand binary numbers which begin
     with the prefix '0b' or '0B'.  The value returned is Octave's default
     numeric class of double, not at unsigned integer class.  Therefore numbers
-    greater than flintmax (2^53) will lose some precision.

  ** The surfnorm function now returns unnormalized (magnitude != 1) normal
