 evaluate the expression \var{x}\code{+}\var{y}, where \var{x} is an
 instance of a class that has an \method{__add__()} method,
-\code{\var{x}.__add__(\var{y})} is called.  Note that
+\code{\var{x}.__add__(\var{y})} is called.  The \method{__divmod__()}
+method should be the equivalent to using \method{__floordiv__()} and
+\method{__mod__()}; it should not be related to \method{__truediv__()}
+(described below).  Note that
 \method{__pow__()} should be defined to accept an optional third
 argument if the ternary version of the built-in
 \function{pow()}\bifuncindex{pow} function is to be supported.
