Hello!
I'm trying to use the contextAlternateIntervals.pl macro but there seem to be a problem with interval of the type:
]-inf, b[ or ]a, inf[
In fact, when trying to use the flag enterIntervals => "alternate", it's not possible to use any infinite endpoint.
The display seem fine, trouble is only on the interval input. Any idea of a workaround? This would be very helpful.
thanks

Can you post a working example of what you are seeing?
Here is the code for the problem. I took of the graphic and text from the exmple since it's not important.
DOCUMENT();
loadMacros(
"PGstandard.pl",
"MathObjects.pl",
"PGcourse.pl",
"AnswerFormatHelp.pl",
"PGgraphmacros.pl",
"unionTables.pl",
"contextAlternateIntervals.pl",
);
TEXT(beginproblem());
Context("AlternateIntervals");
Context()->flags->set(
enterIntervals => "alternate",
displayIntervals => "alternate",
);
#Context("Interval");
$a=random(-10,10);
$choix=random(0,1);
if ($choix == 0) {
$reponse = Interval("]$a,inf[");
} else {
$reponse= Interval("[$a,inf[");
}
ANS(($reponse)->cmp);
and here is the error:
