Name | Description | |
---|---|---|
Clone |
Returns a clone of this object.
| |
Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) | |
Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) | |
GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) | |
GetType | Gets the Type of the current instance. (Inherited from Object.) | |
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) | |
Next |
Returns a nonnegative random number.
| |
NextDouble |
Returns a random number between 0.0 and 1.0.
| |
NextFloat |
Returns a random number between 0.0 and 1.0.
| |
NextLong |
Generates the next pseudorandom, uniformly distributed
long value from this random number generator's sequence.
| |
ToString | Returns a string that represents the current object. (Inherited from Object.) |
MersenneTwister64 generates uniform pseudorandom 64-bit numbers with a period of and a 623-dimensional equidistribution property. See Matsumoto et al. 1998 for details.
Since 64-bit numbers are generated, all of the bits of both nextFloat and nextDouble are pseudorandom.
The series of random numbers can be generated using a seed for initialization or by using an array of type int. One can also save the state of the generator at initialization to be re-used later.
This C# code was translated from the the following C program.
A C-program for MT19937, with initialization improved 2002/1/26. Coded by Takuji Nishimura and Makoto Matsumoto.
Before using, initialize the state by using init_genrand(seed) or init_by_array(init_key, key_length).
