Class PrPTest

java.lang.Object
de.tilman_neumann.jml.primes.probable.PrPTest
public class PrPTest
extends java.lang.Object
A probable prime test for arbitrary precision numbers. For N<32 bit it does trial division. Otherwise it checks the residues of N % 30030, and then does a Miller-Rabin test with Sinclairs bases for N<64 bit, or a BPSW test for larger N. Note that both the Sinclair-Miller-Rabin and BPSW test are considered deterministic prime tests for N<=2^64. See http://en.wikipedia.org/wiki/Baillie-PSW_primality_test and http://miller-rabin.appspot.com/.
