MK> The rand() function will only generate to 5 or 6 decimal MK> places I believe; whereas, the above formula will MK> generate to 10. Which means that it will do a better job MK> of generating large numbers. rand() returns an integer value, not a floating point. The QB and QBasic RND function returns floating point. /* maximum value that can be returned by the rand function. */ #define RAND_MAX 0x7fff The above is from a STDLIB.H file for a C compiler. As you can see, rand() returns a value from 0 to 32767 in this particular implementation. Here is another: #define RAND_MAX 32767 And another: #define RAND_MAX 32767 These are all 16-bit compilers, of course, but my VC++5.0 also gives a maximum value of 0x7fff. > ]* Origin: *YOPS ]I[* 8.4 GIG * RA/FD/FE * Milwaukee, WI (1:154/750) SEEN-BY: 396/1 622/419 632/371 633/260 267 270 371 634/397 635/506 728 SEEN-BY: 639/252 670/213 218 @PATH: 154/750 222 396/1 633/260 635/506 728 633/267 |
