[Octave-bug-tracker] [bug #46493] Incorrect result from fscanf and scanf with %i format

[Philip Nienhuis]

Update of bug #46493 (project octave):

              Item Group:        Incorrect Result => Matlab Compatibility   
                  Status:                 Invalid => None                   
             Open/Closed:                  Closed => Open                   
                 Release:                   4.0.0 => dev

Follow-up Comment #9:

Reopening this report after a more thorough check with Matlab.

Matlab r2014a (empty lines removed):

>> [VAL, COUNT, ERRMSG] = sscanf('''09''', '''%i''')
VAL =
     0
COUNT =
     1
ERRMSG =
Matching failure in format.
>> [VAL, COUNT, ERRMSG] = sscanf('"079"', '"%i"')
VAL =
     7
COUNT =
     1
ERRMSG =
Matching failure in format.
>> 


whereas Octave-4.1.0+ gives:

>> [VAL, COUNT, ERRMSG] = sscanf('''09''', '''%i''')
VAL = 0
COUNT =  1
ERRMSG =
>> [VAL, COUNT, ERRMSG] = sscanf('"079"', '"%i"')
VAL =  7
COUNT =  1
ERRMSG =
>> 


So Matlab, when explicitly queried using the ERRMSG output arg, informs one
that it found illegal characters, while Octave just remains silent.

Release    => dev
Item group => Matlab Compatibility
