I assert nothing, I ask a question.  I just 'automatically' presume that 
zsh calculations will be done  like any normal calculator would  do them.

$ echo $(( 3/8 + 5/8 ))
0

.. if that's what people want, then that's what they'll get, it just seems
a bit strange to me.  I'd say that the very fact that I enter a fraction 
tells
the shell that I'm expecting a real number answer.  Or maybe not.

But that's just my take on it, I'm not saying.  It seems to me that if the
shell accepts the fractions then it should return the correct answer.  I'd
make integer math  the option and have accurate results as the default
but that's just me.
