Type Definition pcg_rand::Pcg64Fast [−][src]
type Pcg64Fast = McgXshRs12864;
A helper definition for a 64bit PCG which is fast but may lack statistical quality.
This generator sacrifices quality for speed by utilizing a Multiplicative Congruential generator instead of a LCG. Additionally it uses a simpler permutation function so that the compiler can optimize and reduce the number of operations.
