 * Version of    : 4 May 1998                                     *
 *----------------------------------------------------------------*
 * This header file exports three types: real, integer, and boole *
 * (short for boolean), as well as the constants TRUE and FALSE.  *
 *                                                                *
 * Users should #include "llnltyps.h" in any file that should     *
 * be easily modifiable to work with different real or integer    *
 * types and use the exported names real and integer within such  *
 * a file. The types for real and integer below have been set to  *
 * double and int, respectively. A user should modify these       *
 * type declarations as he/she sees fit. For example, if a user   *
 * wants the work with type float because double precision        *
 * floating point arithmetic is too expensive on the user's       *
 * machine, then the definition below should be changed to:       *
 *                                                                *
 * typedef float real;                                            *
 *                                                                *
 * Similarly, if a user needs to work with extremely large        *
 * integers (see the system header file <limits.h> for the limits *
 * on type int and long int on your machine), then the user       *
 * should change the definition below to:                         *            
 *                                                                *
 * typedef long int integer;                                      *
 *                                                                *
 * The constants LLNL_FLOAT, LLNL_DOUBLE, LLNL_INT, LLNL_LONG     *
 * indicate the underlying types for real and integer.            *
 * They should be set as follows:                                 *
 *                                                                *
 * (1) #define LLNL_FLOAT 1                                       *
 *     #define LLNL_DOUBLE 0     (real is float)                  *
 *                                                                *
 * (2) #define LLNL_FLOAT 0                                       *
 *     #define LLNL_DOUBLE 1     (real is double)                 *
 *                                                                *
 * (3) #define LLNL_INT 1                                         *
 *     #define LLNL_LONG 0   (integer is int)                     *
 *                                                                *
 * (4) #define LLNL_INT 0                                         *
 *     #define LLNL_LONG 1   (integer is long int)                *
 *                                                                *
 * Thus the legal types for real are float and double, while      *
 * the legal types for integer are int and long int. The macro    *
 * RCONST gives a user a convenient way to define real            *
 * constants. To use the real constant 1.0, for example, the      *
 * user should write                                              *
 *                                                                *
 * #define ONE RCONST(1.0)                                        *
 *                                                                *
 * If real is double, then RCONST(1.0) expands to 1.0. If real is *
 * float, then RCONST(1.0) expands to 1.0F. There is never a      *
 * need to explicitly cast 1.0 to (real).                         *
 *                                                                *

 * name boole (instead of int) is an increase in code readability.*
 * It allows the programmer to make a distinction between int and *
 * boolean data. Variables of type boole are intended to have only*
 * the two values FALSE and TRUE which are defined below to be    *
 * equal to 0 and 1, respectively.                                *
