Wow. I guess in all the years of PHP programming I had never before had
a need for integer arithmetic. In Java, C, Fortran, etc. an integer
slash integer yields an integer. In PHP (I just looked it up) it can be
a float. So, I just assumed that it was the same in PHP. I guess that
this is because PHP is an untyped language.

Yes, I do feel silly now.
