Looks to me like the problem requires an answer with exactly 3 sig figs, but the computers answer (which might be generated algorithmically) has only two sig figs in this particular instance. If you are the author, you might change that by specifying 2E format for the answer display.<br>
Alternatively, you 'might' ensure that the answers do not ever come out to be an exact multiple (of 1E7, in this case).<br><br>If you are not the author, then you might, as course coordinator, change the minimum sig figs allowed to be less than 3.<br>

<br><tt><font size="2">"Description: Over the 2-3 years I have been
using LON-CAPA I have not been able to figure out the following error that
comes up periodically:<br>
ERROR: Computer's answer is incorrect ("280000000"). It is likely
that the tolerance range [279972000, 280028000] or significant figures
[3s, 3s] need to be adjusted. As far as I can tell the problem works appropriately,
but it plants bombs and floods my e-mail. Can you explain how to
avoid this error?</font></tt><font size="2" face="sans-serif">"</font>

<br><font size="2" face="sans-serif">I'm seeing a couple of posts to the
mailing list stating that it is "one of lon-capa's oldest bugs",
but I don't really see the explanation she needs. Any help on how to avoid
the error would be appreciated.<br>
