[Octave-bug-tracker] [bug #47741] The scanf family of functions cannot parse 64bit hex numbers on Windows and 32bit Linux

[Markus Mützel]

Follow-up Comment #4, bug #47741 (project octave):

Some examples in Matlab on Windows:

>> sscanf('1000000000', '%d')
ans =
   1.0000e+09
>> class(ans)
ans =
double
>> sscanf('3000000000', '%d')
ans =
   2.1475e+09
>> class(ans)
ans =
double
>> sscanf('6000000000', '%d')
ans =
   2.1475e+09
>> class(ans)
ans =
double
>> sscanf('6000000000', '%ld')
ans =
           6000000000
>> class(ans)
ans =
int64
>> sscanf('ffff', '%x')
ans =
       65535
>> class(ans)
ans =
double
>> sscanf('ffff', '%lx')
ans =
                65535
>> class(ans)
ans =
uint64
>> sscanf('6000000000 6000000000', '%ld %d')
ans =
   1.0e+09 *
    6.0000
    2.1475
>> class(ans)
ans =
double
>> sscanf('6000000000 ffff', '%ld %lx')
ans =
   1.0e+09 *
    6.0000
    0.0001
>> class(ans)
ans =
double


The same in Octave 4.0.1 on Windows:

>> sscanf('1000000000', '%d')
ans =   1.0000e+009
>> class(ans)
ans = double
>> sscanf('3000000000', '%d')
ans = [](0x1)
>> class(ans)
ans = double
>> sscanf('6000000000', '%d')
ans = [](0x1)
>> class(ans)
ans = double
>> sscanf('6000000000', '%ld')
ans = [](0x1)
>> class(ans)
ans = double
>> sscanf('ffff', '%x')
ans =  65535
>> class(ans)
ans = double
>> sscanf('ffff', '%lx')
ans =  65535
>> class(ans)
ans = double
>> sscanf('6000000000 6000000000', '%ld %d')
ans = [](0x1)
>> class(ans)
ans = double
>> sscanf('6000000000 ffff', '%ld %lx')
ans = [](0x1)
>> class(ans)
ans = double
