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

[Mike Miller]

Follow-up Comment #5, bug #47741 (project octave):

I've got a partial solution for the main issue in this bug report, see
attached.

Do we want to make %h[dioux] mean exactly a 16-bit integer as Markus
recommended in the original post? If we have to make "l" mean a 64-bit integer
for Matlab compatibility, then I kind of like Markus' idea of making the "h"
modifier mean exactly 16-bit and no modifier exactly 32-bit for symmetry.

There are other related issues that should probably be reported separately,
such as scanf should return an array of type int64/uint64 if the only
conversion is %l[dioux]. And that Matlab returns a saturated integer when the
number read is out of range, while Octave aborts conversion at that point.
