Constructor & Destructor Documentation

planck_rng()

planck_rng::planck_rng ( unsigned int  x1 = 123456789, unsigned int  y1 = 362436069, unsigned int  z1 = 521288629, unsigned int  w1 = 88675123  )

inline

Initializes the generator with 0 to 4 seed values.

Member Function Documentation

seed()

void planck_rng::seed ( unsigned int  x1 = 123456789, unsigned int  y1 = 362436069, unsigned int  z1 = 521288629, unsigned int  w1 = 88675123  )

inline

Re-initializes the generator with 0 to 4 seed values.

Definition at line 90 of file planck_rng.h.

int_rand_uni()

unsigned int planck_rng::int_rand_uni ( )

inline

Returns uniformly distributed random integer numbers from the interval [0;0xFFFFFFFF].

Definition at line 100 of file planck_rng.h.

rand_gauss()

double planck_rng::rand_gauss ( )

inline

Returns random numbers with Gaussian distribution (mean=0, sigma=1).

Uses rand_uni() internally.

Definition at line 118 of file planck_rng.h.

rand_exp()

double planck_rng::rand_exp ( )

inline

Returns exponentially distributed random numbers (mean=1, nonnegative)

Uses rand_uni() internally.

Definition at line 145 of file planck_rng.h.
