Detailed Description

Random number generator.

Implementation of a pseudorandom number generator. The generator in described in the paper "Mersenne Twister: A 623-dimensionally equidistributed uniform pseudorandom number generator" by Makoto Matsumoto and Takuji Nishimura. The implementation is MT-safe.

Member Function Documentation

getDouble()

static double RandomLegacy::getDouble ( )

inlinestaticnoexcept

Returns a random real number in the range [0;1].

getFloat()

static float RandomLegacy::getFloat ( )

inlinestaticnoexcept

Returns a random real number in the range [0;1].

getInteger()

static unsigned int RandomLegacy::getInteger ( )

staticnoexcept

Returns a random integer (unsigned) utilizing the full range of the type.

inlinestaticnoexcept

Returns a random real number in the range [0;1].

randomize() [1/2]

static void RandomLegacy::randomize ( )

staticnoexcept

Initializes the internal state of the generator from the current time.

randomize() [2/2]

static void RandomLegacy::randomize ( unsigned int  seed )

staticnoexcept

Parameters

seed	The desired seed (generator does not work with zero).
