| void | spot::srand (unsigned int seed) |
| Reset the seed of the pseudo-random number generator. More... | |
| int | spot::rrand (int min, int max) |
| Compute a pseudo-random integer value between min and max included. More... | |
| int | spot::mrand (int max) |
| Compute a pseudo-random integer value between 0 and max-1 included. More... | |
| double | spot::drand () |
| Compute a pseudo-random double value between 0.0 and 1.0 (1.0 excluded). More... | |
| double | spot::nrand () |
| Compute a pseudo-random double value following a standard normal distribution. (Odeh & Evans) More... | |

| void | spot::mrandom_shuffle (iterator_type &&first, iterator_type &&last) |
| Shuffle the container using mrand function above. This allows to get rid off shuffle or random_shuffle that use uniform_distribution and RandomIterator that are not portables. More... | |

#include <spot/misc/random.hh>
Compute a pseudo-random double value following a standard normal distribution. (Box-Muller)
This uses the polar form of the Box-Muller transform to generate random values.
| double spot::drand | ( | ) |
| int spot::mrand | ( | int | max | ) |
#include <spot/misc/random.hh>
Compute a pseudo-random integer value between 0 and max-1 included.

#include <spot/misc/random.hh>
Compute a pseudo-random double value following a standard normal distribution. (Odeh & Evans)
This uses a polynomial approximation of the inverse cumulated density function from Odeh & Evans, Journal of Applied Statistics, 1974, vol 23, pp 96-97.
