Webwork 2.1.3 with the new parser enabled.

minf entered as an answer is displayed as regular infinity. The generated image has: alt="\infty" in the html. The problem uses the code:

$ans1 = 'MINF';

&ANS(std_num_str_cmp($ans1,['INF','MINF']));

Found the reason (I think) in PGanswermacros.pl v1.35, line 1081 where inf and -inf are parsed into tex. The m is jettisoned in the parsing.

Changing MINF to -INF everywhere in the pg file corrects the problem.

OOPS! Sorry, that was my fault. I have fixed the code so that it works for MINF now. You can get an updated copy of PGanswermacros.pl from the CVS archive.
