What is supposed to be the meaning of "quo" and "exquo" in the Polys? Looking
in densearith.py, I see things like this:
def dup_quo(f, g, K):
"""Returns polynomial quotient in `K[x]`. """
q, r = dup_div(f, g, K)
if not r:
return q
else:
raise ExactQuotientFailed('%s does not divide %s' % (g, f))
def dup_exquo(f, g, K):
"""Returns exact polynomial quotient in `K[x]`. """
return dup_div(f, g, K)[0]
But I would have expected the exact opposite: for quo to give be the quotient
without caring and for exquo to warn me when the quotient is not exact. So
what is the reasoning behind the current behavior?
