Detailed Description

Static wrapper around RandomEngine for convenience.

Provides simple functions to seed the global engine and generate random values of various types and ranges.

Member Function Documentation

Double() [1/2]

double Crux::Random::Double ( )

static

Returns a pseudorandom double in [0.0, 1.0).

Returns

Random double in [0.0, 1.0).

Double() [2/2]

double Crux::Random::Double ( double max = 1.0 )

static

Returns a pseudorandom double in [0.0, 1.0).

Parameters

max	Exclusive upper bound. Defaults to 1.0.

Returns

Random double in [0.0, max).

Float() [1/2]

float Crux::Random::Float ( )

static

Returns a pseudorandom float in [0.0f, 1.0f).

Returns

Random float in [0.0, 1.0).

Float() [2/2]

float Crux::Random::Float ( float max )

static

Returns a pseudorandom float in [0.0f, max).

Parameters

max	Exclusive upper bound.

Returns

Random float in [0.0, max).

Int() [1/2]

unsigned int Crux::Random::Int ( )

static

Returns a pseudorandom integer in [0, UINT_MAX].

Returns

Random unsigned integer.

Int() [2/2]

unsigned int Crux::Random::Int ( int max = 100 )

static

Returns a pseudorandom integer in [0, max).

Parameters

max	Exclusive upper bound. Defaults to 100.

Returns

Random integer in [0, max).

Seed()

void Crux::Random::Seed ( unsigned long long seed = 0ULL )

static

Seeds the internal RandomEngine.

Parameters

seed	The 64-bit seed value. If zero, uses default state/stream.

U64()

unsigned long long Crux::Random::U64 ( )

static

Returns a pseudorandom 64-bit unsigned integer.

Combines two 32-bit Next() calls from the engine into one u64.

Returns

Random 64-bit unsigned integer.
