Random Number Methods

void random_set_seed (unsigned int seed)
Sets the seed for the global random number generator, which is used by the G::random_* methods, to seed.
bool random_boolean ()
Gets a random boolean value (this corresponds to a unbiased coin toss).
unsigned int random_int ()
Gets a random unsigned integer equally distributed over the range [0..2^32-1].
int random_int_range (int begin, int end)
Gets a random integer equally distributed over the range [begin..end-1].
double random_double ()
Gets a random double equally distributed over the range [0..1).
double random_double_range (double begin, double end)
Gets a random double equally distributed over the range [begin..end).

Detailed Description

A C++ interface for GRand.

Provides Rand, pseudo-random number generator.

Function Documentation

bool random_boolean ( )

Gets a random boolean value (this corresponds to a unbiased coin toss).

Returns:
A random bool value.

double random_double ( )

Gets a random double equally distributed over the range [0..1).

Returns:
A random number.

double random_double_range ( double begin,

double end

)

Gets a random double equally distributed over the range [begin..end).

Parameters:

begin The lower closed bound of the interval.

end The upper open bound of the interval.

Returns:
A random number.

unsigned int random_int ( )

Gets a random unsigned integer equally distributed over the range [0..2^32-1].

Returns:
A random number.

int random_int_range ( int begin,

int end

)

Gets a random integer equally distributed over the range [begin..end-1].

Parameters:

begin The lower closed bound of the interval.

end The upper open bound of the interval.

Returns:
A random number.

void random_set_seed ( unsigned int seed )

Sets the seed for the global random number generator, which is used by the G::random_* methods, to seed.

Parameters:

seed A value to reinitialize the global random number generator.
