|Hi John, |
Thanks. You are correct --- there is a bug. As you pointed out (private
email), one way to fix this is (in PGanswermacros.pl) to change the
parameter "tolerance" to "tol" in the two places it appears in sub
std_num_cmp_abs. But the root cause of this is actually a bug in
num_cmp. This has been fixed in the most recent version
PGanswermacros.pl which you can download if you want --- see below.
Note that very few problems use std_num_cmp_abs, etc. so that most
WeBWorK users will never see this bug and can safely continue using the
version of 1.7.02 version of PGanswermacros.pl.
You can download the current version of PGanswermacros.pl from the CVS repository:
