+<dd><p>The return value is of type <code>REAL</code> with the kind type parameter of the
+argument if the optional <var>KIND</var> is absent; otherwise, the kind
+type parameter will be given by <var>KIND</var>.  If the magnitude of 
+<var>X</var> is less than one, <code>AINT(X)</code> returns zero.  If the
+magnitude is equal to or greater than one then it returns the largest
+whole number that does not exceed its magnitude.  The sign is the same
