ozo: I figured "math" was too general of a division, but I've read that function/procedure names are too specific. Where does the line get drawn?
A Perl module is simply one or more files that conform to the construct for a Perl module that perform a particular task and call be called by Perl scripts.
There's nothing to stop someone creating a module called:
Life::Universe::Everything
that does absolutely everything, but in general, most Perl modules perform a specific set of tasks.

What features should a program have?
It depends what the creator of the program wants to accomplish,
the usefulness of a feature compared to the complication of having to select the feature,
the programming effort to add a feature compared to adapting a another program to perform the desired function,
users expectations due to experience with similar programs,
the kinds of task the use is likely to want to perform together,
etc.

There is no standard module called named just "math", but you can write one yourself, and include whatever you want in it.
