Detailed Description

The TT800 random number generator.

The TT800 generator has high quality with a period of 2^800. The TT800 is a light version of the Mersenne-Twister generator.

Constructor & Destructor Documentation

◆ TT800() [1/2]

Murl::Util::TT800::TT800 ( )

The default constructor.

Seed() the random number generator with the current time nanoseconds fraction.

◆ TT800() [2/2]

Murl::Util::TT800::TT800 ( UInt32  seed)

Constructor taking a seed value.

Parameters
seedThe seed value.

Member Function Documentation

◆ Seed()

virtual void Murl::Util::TT800::Seed ( UInt32  seed)
virtual

Seed the random number generator.

The seed is used for a temporary Marsaglia generator which is used for initializing the internal 800 bit state.

Parameters
seedThe seed value.

Implements Murl::Util::Rng.

◆ Rand()

virtual UInt32 Murl::Util::TT800::Rand ( )
virtual

Get a random number in the full UInt32 range.

Returns
The random number.

Implements Murl::Util::Rng.
