[Octave-bug-tracker] [bug #51515] sprintf not rounding as Matlab does

[Rik]

Update of bug #51515 (project octave):

                Severity:              3 - Normal => 2 - Minor              
                Priority:              5 - Normal => 3 - Low

Follow-up Comment #5:

Thanks for testing.  Hopefully someone else can try a different platform just
to be sure.  For example, this article from Stack Overflow
(https://stackoverflow.com/questions/31142600/c-rounding-behavior-consistency-for-ties-with-sprintf)
shows that Windows Visual Studio and GCC perform different rounding in exactly
the way you are experiencing.

The simplest thing, for the moment, would be to call round() yourself on any
data you want formatted in a particular fashion.

The rounding mode could be set as a whole for the C math library by using
fsetround.  But that might be overkill for this.
