The Mersenne Twister algorithm creates 624 random numbers and presents them one at a time. Consequently, every 624th value you retrieve will take longer than the others. It is still a fast and well dispersed algorithm.
This version initially seeds itself from the system clock but can be seeded manually as well. The methods are all static. The fastest return is DWORD Get() a double GetDouble() is also provided. There are also two methods taking bounding values which return random numbers in the interval [a,b]:
DWORD Get(DWORD a, DWORD b); double Get(double a, double b);Usage:gColor::gColor(bool Grey) : R(Twister::GetDouble()), G(Twister::GetDouble()), B(Twister::GetDouble()), A(Twister::GetDouble()) {if(Grey) R=G=B;}
