◆ drand()

double spot::drand ( )

#include <spot/misc/random.hh>

Compute a pseudo-random double value between 0.0 and 1.0 (1.0 excluded).

◆ mrandom_shuffle()

template<class iterator_type >
void spot::mrandom_shuffle ( iterator_type &&  first,
iterator_type &&  last 
)

#include <spot/misc/random.hh>

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.

References spot::mrand().

◆ nrand()

double spot::nrand ( )

#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.

◆ rrand()

int spot::rrand ( int  min,
int  max 
)

#include <spot/misc/random.hh>

Compute a pseudo-random integer value between min and max included.

See also
drand, mrand, srand

◆ srand()

void spot::srand ( unsigned int  seed)

#include <spot/misc/random.hh>

Reset the seed of the pseudo-random number generator.
