[Octave-bug-tracker] [bug #49559] Implementation of containers.Map

[Rik]

Follow-up Comment #17, bug #49559 (project octave):

@jwe: Your code does correctly handle intmax, however Map is now back to
failing to sort numeric keys with negative values correctly.


m = containers.Map('KeyType','double','ValueType','char');
m(-2)='a';
m(-1)='b';
m(0)='c';
m(1)='d';
m(2)='e';
keys (m)
ans =
{
  [1,1] = 0
  [2,1] =  1
  [3,1] =  2
  [4,1] = -1
  [5,1] = -2
}


You could save the signbit separately at the front of the string that is
produced.  Or you could decode numeric keys back from strings to numbers, sort
them, and pass the sorted list to orderfields rather than relying on the
default.  There's probably some other strategies that work.
