[Octave-bug-tracker] [bug #61132] Colon operator fails for int64 and uint64

[anonymous]

Follow-up Comment #4, bug #61132 (project octave):

Hello jwe. A follow-up problem for all unsigned integer types, not just
uint64.


hi = intmax("uint64");  # OK
lo = hi-99;             # OK
up = lo:hi;             # OK
down = hi:-1:lo;        # error: colon operator increment invalid (not an
integer or out of range for given integer type)
down = fliplr(up);      # current workaround to the error
charup = 'a':'z';       # for comparison. this is OK.
chardown = 'z':-1:'a';  # for comparison. this is OK too!


Is this a conscious limit that one cannot construct descending ranges for
unsigned integer types with the colon operator or is it a bug?
