Well, jdporter says: "handle the arg list being empty. You probably don't want to throw a divide-by-zero exception."

I am actually fine with that error code!

I have written Perl code that intercepts various warnings in situations where I can actually fix the problem. I remember one sort routine where a numeric comparison didn't work and the code defaulted back to an alpha comparison. There is no "fix" for a "divide by zero".

I added comments about this in further code. Grandfather is right about that. Document limitations.
In the code, allowing Perl to throw a "divide by zero" exception is fine.
The code is short. Detecting and printing an error that "will happen" is unnecessary, because there is no "fix" for that error.
