Member Function Documentation

getNext()

uint64 iaux::iaRandomNumberGenerator::getNext

(

)

Returns

next random number

getNextFloat()

float64 iaux::iaRandomNumberGenerator::getNextFloat

(

)

Returns

next random number as float 0.0-1.0

getNextFloatRange()

float64 iaux::iaRandomNumberGenerator::getNextFloatRange	(	float64	min,
		float64	max
	)

Returns

next random number as float min-max

Parameters

min	the min value returned
max	the max value returned

getNextRange() [1/2]

int64 iaux::iaRandomNumberGenerator::getNextRange	(	int64	min,
		int64	max
	)

Returns

next random number [min, max]

Parameters

min	the min value returned
max	the max value returned

getNextRange() [2/2]

int64 iaux::iaRandomNumberGenerator::getNextRange

(

int64

range

)

Returns

next random number [0, range-1]

Parameters

range

the range of values

getNextRangeExponentialDecrease()

int64 iaux::iaRandomNumberGenerator::getNextRangeExponentialDecrease	(	int64	min,
		int64	max,
		float64	lambda
	)

Returns

next random number with exponential distribution [min, max]

high chances towards min and lower chances towards max

Parameters

min	the min value returned
max	the max value returned
lambda	this value determines where the median of the distribution curve lies before it gets scaled back to the min max range

getNextRangeExponentialIncrease()

int64 iaux::iaRandomNumberGenerator::getNextRangeExponentialIncrease	(	int64	min,
		int64	max,
		float64	lambda
	)

Returns

next random number with exponential distribution [min, max]

high chances towards max and lower chances towards min

Parameters

min	the min value returned
max	the max value returned
lambda	this value determines where the median of the distribution curve lies before it gets scaled back to the min max range

setSeed()

void iaux::iaRandomNumberGenerator::setSeed

(

uint64

seed

)

sets the seed

Parameters

seed

the seed
