mersenne_twister_engine
is a random number engine based on Mersenne Twister algorithm. It produces high quality unsigned integer random numbers.
The following typedefs define the random number engine with two commonly used parameter sets:

[edit] Member types
Member type | Definition |
result_type
|
The integral type generated by the engine. Results are undefined if this is not an unsigned integral type. |
[edit] Member functions
Construction and Seeding |
|
constructs the engine (public member function) |
|
sets the current state of the engine (public member function) |
|
Generation |
|
advances the engine's state and returns the generated value (public member function) |
|
advances the engine's state by a specified amount (public member function) |
|
Characteristics |
|
[static]
|
gets the smallest possible value in the output range (public static member function) |
[static]
|
gets the largest possible value in the output range (public static member function) |
[edit] Non-member functions
compares the internal states of two pseudo-random number engines (function template) |
|
performs stream input and output on pseudo-random number engine (function template) |
