Init()

void Init

(

UInt32

s

)

Initializes the random number sequence from a starting seed. Each seed will give a different sequence of random numbers.

Parameters

[in]

s

The initial seed to start the random number sequence.

Get01()

Float Get01

(

)

Gets a random value between 0 and 1.

Returns

A random value in the range [0, 1].

Get11()

Float Get11

(

)

Gets a random value between -1 and +1.

Returns

A random value in the range [-1, +1].

GetG01()

Float GetG01

(

)

Gets a random value between 0 and 1 with Gaussian distribution.

Returns

A random value in the range [0, 1] with Gaussian distribution.

GetG11()

Float GetG11

(

)

Gets a random value between -1 and +1 with Gaussian distribution.

Returns

A random value in the range [-1, +1] with Gaussian distribution.

GetSeed()

Int32 GetSeed

(

)

const

Gets the seed representing the current state of the random number generator.

Returns

The current seed.
