| struct | mt |
| Structure to hold MT algorithm state to easily allow independant sets of random numbers with different seeds. More... | |
Functions | |
| void | mt_init (mt *mt, unsigned int seed) |
| Initialize a new MT state with a given seed. | |
| unsigned int | mt_rand32 (mt *mt) |
| Generate a new 32-bit random number based on the given MT state. | |
| double | mt_rand (mt *mt) |
| Generate a new random number between [0.0, 1.0) based on the given MT state. | |
| void | sg_srandom_time () |
| Seed the random number generater with time() so we don't see the same sequence every time. | |
| void | sg_srandom_time_10 () |
| Seed the random number generater with time() in 10 minute intervals so we get the same sequence within 10 minutes interval. | |
| void | sg_srandom (unsigned int seed) |
| Seed the random number generater with your own seed so can set up repeatable randomization. | |
| double | sg_random () |
| Return a random number between [0.0, 1.0). | |

| double sg_random | ( | ) |
Return a random number between [0.0, 1.0).
Definition at line 106 of file sg_random.c.
| void sg_srandom | ( | unsigned int | seed | ) |
Seed the random number generater with your own seed so can set up repeatable randomization.

| void sg_srandom_time_10 | ( | ) |
Seed the random number generater with time() in 10 minute intervals so we get the same sequence within 10 minutes interval.
This is useful for synchronizing two display systems.
