-@deftypefun {long double} dreml (long double @var{numerator}, long double @var{denominator})
+@deftypefunx float dremf (float @var{numerator}, float @var{denominator})
+@deftypefunx {long double} dreml (long double @var{numerator}, long double @var{denominator})
 These functions are like @code{fmod} etc except that it rounds the
 internal quotient @var{n} to the nearest integer instead of towards zero
 to an integer.  For example, @code{drem (6.5, 2.3)} returns @code{-0.4},
