public class RandMT : RandCustomBase

The RandMT type exposes the following members.

Constructors
 NameDescription
Public methodRandMT() Creates a random number generator with a random seed.
Public methodRandMT(Int32) Creates a random number generator seeded with a specified integer.
Public methodRandMT(Int32[]) Creates a random number generator seeded with a specified integer array.

Methods
 NameDescription
Public methodNextDouble53This method was in the original C code. It is probably a cryptic way of combining two 32-bit numbers into a 64-bit number which then has 53 bits converted into a floating-point number so that all possible values can be produced. A shift-and-multiply is an easier way to do that. This method remains in the class as a reference.
Public methodNextInt64
(Overrides RandCustomBase.NextInt64())
Public methodRandUint32 Generates a random unsigned integer in the interval [0,0xFFFFFFFF]. This methods was a public function in the original C code, so it remains here as a reference. It is not part of the standard Random class interface.

Remarks

Long running tests have observed the expected minimum values Next 0 (0x0) and Core 0.0 and the expected maximum Next 2147483646 (0x7FFFFFFE) from Core 0.999999999790607.
