-This function is almost the same as @code{eq}, except that if @var{a}

-equality (as if by @code{equal} instead of @code{eq}).  This makes a
-difference only for versions of Emacs that are compiled with
-floating-point support.  Emacs floats are allocated
-objects just like cons cells, which means that @code{(eq 3.0 3.0)}
-will not necessarily be true---if the two @code{3.0}s were allocated
-separately, the pointers will be different even though the numbers are
-the same.  But @code{(eql 3.0 3.0)} will always be true.
-
-The types of the arguments must match, so @code{(eql 3 3.0)} is
-still false.
-
-Note that Emacs integers are ``direct'' rather than allocated, which
-basically means @code{(eq 3 3)} will always be true.  Thus @code{eq}
-and @code{eql} behave differently only if floating-point numbers are
-involved, and are indistinguishable on Emacs versions that don't
-support floats.
-
-There is a slight inconsistency with Common Lisp in the treatment of
-positive and negative zeros.  Some machines, notably those with IEEE
-standard arithmetic, represent @code{+0} and @code{-0} as distinct
-values.  Normally this doesn't matter because the standard specifies
-that @code{(= 0.0 -0.0)} should always be true, and this is indeed
-what Emacs Lisp and Common Lisp do.  But the Common Lisp standard
-states that @code{(eql 0.0 -0.0)} and @code{(equal 0.0 -0.0)} should
-be false on IEEE-like machines; Emacs Lisp does not do this, and in
-fact the only known way to distinguish between the two zeros in Emacs
