Re: Divide by zero and monitor group...

I'm playing devils-advocate, here... By and large I do agree with your
premise, but there are sometimes exceptions to the rule that "monitor should
only be used for unexpected errors".

There are some advantages in code readability to using monitor blocks for
naturally occurring errors, however.

Besides the performance, it's worth considering the code readability.
A monitor group is particularly attractive if the alternative
(checking beforehand to ensure the error condition(s) can't occur)
makes the main logic of your code much more verbose or much harder to
read.
