-To compute the overall error on argument reduction\footnote{Note that this error analysis is correct even in the face of misrounding.  Misrounding can combine with the argument reduction error, though, to cause $\abs{y - {\gd y}}$ to move farther above $\frac{\Pi}{4}$}, first remember that, from equation (\ref{eqnpitwoterms}), we have:
