Math-Prime-Util-0.45

Changes for version 0.45 - 2014-09-26

ADDED
- forcomb { ... } n, k combinations iterator
- forperm { ... } n permutations iterator
- factorial(n) n!
- is_bpsw_prime(n) primality test with no pretests, just ES BPSW
- is_frobenius_pseudoprime Frobenius quadratic primality test
- is_perrin_pseudoprime Perrin primality test (unrestricted)
- vecmin(@list) minimum of list of integers
- vecmax(@list) maximum of list of integers
- vecprod(@list) product of list of integers
- bernfrac(n) (num,den) of Bernoulli number
- bernreal(n) Bernoulli number as BigFloat
- stirling(n,m,[type]) Stirling numbers of first or second kind
- LambertW(k) Solves for W in k = W*exp(W)
- Pi([digits]) Pi as NV or with requested digits
FUNCTIONALITY AND PERFORMANCE
- znorder algorithm changed from Das to Cohen for ~1% speedup.
- factoring sped up a bit for 15-19 digits.
- speedup for divisor_sum with very large exponents.
OTHER
- Alias added for the module name "ntheory". The module has grown enough that it seems more appropriate.
- Big build change: Try a GMP compilation and add Math::Prime::Util::GMP to dependency list if it succeeds.
- Fixed a memory leak in segment_primes / segment_twin_primes introduced in previous release. Thanks Valgrind!
