In addition fast functions for\ngenerating random numbers according to a uniform, normal and\nexponential distribution are included. The latter two use the\nZiggurat algorithm originally proposed by Marsaglia and Tsang\n(2000, ). The fast sampling methods\nsupport unweighted sampling both with and without replacement.\nThese functions are exported to R and as a C++ interface and\nare enabled for use with the default 64 bit generator from the\nPCG family, Xoroshiro128+/++/** and Xoshiro256+/++/** as well\nas the 64 bit version of the 20 rounds Threefry engine (Salmon\net al., 2011, ) as provided by the\npackage
