I will post the URL of the fixed macro and how-to fix it for your

This was reported in 2018 @ <a class="moz-txt-link-freetext"
href="http://bugzilla.scilab.org/15836" moz-do-not-send="true">http://bugzilla.scilab.org/15836</a>
and is still unfixed.<br>
<br>
For bitget, i will see how to do, if there is a workaround. If
not, at least warn users in the help page.<br>

is a bug. <br>
bitget.tst tests int64 and uint64 cases with other inttypes: <br>
--> edit
SCI\modules\elementary_functions\tests\unit_tests\bitget.tst <br>
<br>
When bitget() has been extended to 64 bits integers ~3 years
ago, several bugs have appeared about the processing of these
integers by other Scilab functions, noticeably some functions
involved in the bitget implementation. <br>
Not all are fixed (actually, only few of them are fixed). <br>
But maybe it's another issue here. I could have a look, about
this specific case. <br>
<br>
If you can do other tests and get issues, please report all of
them on bugzilla. <br>
Thanks <br>
