+
+These	functions  compute the remainder and part of the quotient upon division
+of @var{numerator} by @var{denominator}. A few bits of the quotient are stored
+via the @var{quo} pointer. The remainder is returned as function value.
+
+The value of the remainder is the same as that computed by the
@code{remainder}
+function above. The value stored via the @var{quo} pointer has the sign of
+@var{numerator}/@var{denominator} and agrees with the quotient in at least the
+low order 3 bits.
+
+For example, @code{remquo(29.0,3.0)} returns @code{-1.0} and might store
@code{2}.
+Note that the actual quotient might not fit in an integer.
