sympy 部门文档术语混淆

sympy division documentation terminology confusion

关于官方 sympy 文档:https://docs.sympy.org/latest/modules/polys/basics.html#division 它说:

The function div() provides division of polynomials with remainder. 
That is, for polynomials f and g, it computes q and r, such that 
=⋅+ and deg()<. For polynomials in one variables with coefficients 
in a field, say, the rational numbers, q and r are uniquely defined 
this way:

请注意上面写着 deg(r)<q。他们的意思是说 deg(r)<deg(q) 吗?

我不小心在这个问题上悬赏了。我在这里回答我自己的问题,试图结束这个问题。
