Detailed Description

wrapper for one random number generator

if you need individual random number generators use iaRandomNumberGenerator instead of iaRandom

Member Function Documentation

getNext()

uint64 iaux::iaRandom::getNext ( )

static

Returns

next random number

getNextFloat()

float64 iaux::iaRandom::getNextFloat ( )

static

Returns

next random number as float 0.0-1.0

getNextFloatRange()

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

static

Returns

next random number as float min-max

Parameters

min	the min value returned
max	the max value returned

getNextRange() [1/2]

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

static

Returns

next random number [min, max]

Parameters

min	the min value returned
max	the max value returned

getNextRange() [2/2]

int64 iaux::iaRandom::getNextRange ( int64  range )

static

Returns

next random number [0, range-1]

Parameters

range

the range of values

getNextRangeExponentialDecrease()

int64 iaux::iaRandom::getNextRangeExponentialDecrease ( int64  min, int64  max, float64  lambda = 2.0  )

static

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::iaRandom::getNextRangeExponentialIncrease ( int64  min, int64  max, float64  lambda = 2.0  )

static

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

setSeed()

void iaux::iaRandom::setSeed ( uint64  seed )

static

sets the seed

Parameters

seed

the seed
