Mcg59(int seed, bool threadSafe)

Initializes a new instance of the Mcg59 class.
The seed is set to 1, if the zero is used as the seed.
Parameters
int seed

The seed value.

bool threadSafe

if set to true , the class is thread safe.

Mcg59(bool threadSafe)

Initializes a new instance of the Mcg59 class using a seed based on time and unique GUIDs.
Parameters
bool threadSafe

if set to true , the class is thread safe.

Mcg59()

Initializes a new instance of the Mcg59 class using a seed based on time and unique GUIDs.

Mcg59(int seed)

Initializes a new instance of the Mcg59 class.
If the seed value is zero, it is set to one. Uses the value of ThreadSafeRandomNumberGenerators to set whether the instance is thread safe.
Parameters
int seed

The seed value.

Public Static Functions

void Doubles(Double[] values, int seed)

Fills an array with random numbers greater than or equal to 0.0 and less than 1.0.
Supports being called in parallel from multiple threads.

Double[] Doubles(int length, int seed)

Returns an array of random numbers greater than or equal to 0.0 and less than 1.0.
Supports being called in parallel from multiple threads.

IEnumerable<double> DoubleSequence(int seed)

Returns an infinite sequence of random numbers greater than or equal to 0.0 and less than 1.0.
Supports being called in parallel from multiple threads, but the result must be enumerated from a single thread each.
