+/* REAL.H: include file to support compile-time specification of precision  */
+/* in floating-point calculations.  If the DOUBLEPREC symbol is defined to  */
+/* the preprocessor, calculations are done in double precision; otherwise,  */
+/* they may be done in single precision.                                    */

+/* Rationale: ANSI C enables programmers to write single-precision code,    */
+/* but does not make it easy to change the precision of code at compile     */
+/* time, since different functions names are used for floating and double   */
+/* calculations.  This package introduces the keyword "real", which may be  */
+/* either float or double, and defines functions which compute with         */
+/* real-valued numbers.                                                     */
