0.57 2016-01-03
[ADDED]
- formultiperm { ... } \@n loop over multiset permutations
- todigits(n[,base[,len]]) convert n to digit array
- todigitstring(n[,base[,len]]) convert n to string
- fromdigits(\@d[,base]) convert digit array ref to number
- fromdigits(str[,base]) convert string to number
- ramanujan_prime_count counts Ramanujan primes in range
- vecany { expr } @n true if any expr is true
- vecall { expr } @n true if all expr are true
- vecnone { expr } @n true if no expr are true
- vecnotall { expr } @n true if not all expr are true
- vecfirst { expr } @n returns first element with expr true
[FUNCTIONALITY AND PERFORMANCE]
- nth_ramanujan_prime(997) was wrong. Fixed.
- Tighten Ramanujan prime bounds. Big speedups for large nth Rp.
0.56 2015-12-13
[ADDED]
- is_carmichael(n) Returns 1 if n is a Carmichael number
- forcomp { ... } n[,{...}] loop over compositions
[FUNCTIONALITY AND PERFORMANCE]
- Faster, nonrecursive divisors_from_factors routine.
- gcdext(0,0) returns (0,0,0) to match GMP and Pari/GP.
- Use better prime count lower/upper bounds from B羹the 2015.
- forpart and forcomp both use lexicographic order (was anti-lexico).
0.55 2015-10-19
- Fixed test that was using a 64-bit number on 32-bit machines.
[FUNCTIONALITY AND PERFORMANCE]
- Speed up PP versions of sieve_prime_cluster, twin_primes,
twin_prime_count, nth_twin_prime, primes.
0.54 2015-10-14
[ADDED]
- sieve_prime_cluster(low,high[,...]) find prime clusters
[Misc]
- Certain small primes used to return false with Frobenius and AES Lucas
tests when given extra arguments. Both are unusual cases never used
by the main system. Fixed.
0.53 2015-09-05
[ADDED]
- ramanujan_tau(n) Ramanujan's Tau function
- sumdigits(n[,base]) sum digits of n
[FUNCTIONALITY AND PERFORMANCE]
- Don't use Math::MPFR unless underlying MPFR library is at least 3.x.
- Use new Math::Prime::Util::GMP::sigma function for divisor_sum.
- Use new Math::Prime::Util::GMP::sieve_twin_primes(a,b).
0.52 2015-08-09
[ADDED]
- is_square_free(n) Check for repeated factors
[FUNCTIONALITY AND PERFORMANCE]
- print_primes with 2 args was sending to wrong fileno.
- Double speed of sum_primes.
- Rewrote some internal sieve-walking code, speeds up next_prime,
forprimes, print_primes, and more.
- Small speedup for forcomposites / foroddcomposites.
- Small speedup for is_prime with composite 32+ bit inputs.
- is_frobenius_khashin_pseudoprime now uses Montgomery math for speed.
- PrimeArray now treats skipping forward by relatively small amounts as
forward iteration. This makes it much more efficient for many cases,
but does open up some pathological cases.
- PrimeArray now allows exporting @primes (and a few others), which
saves some typing.
- PrimeArray now works for indices up to 2^32-1, after which it silently
rolls over. Previously it worked to 2^31-1 then croaked.
- PrimeIterator now uses small segments instead of always next_prime.
A little more memory, but 2-4x faster.
- factor, divisor, fordivisors and some others should better keep
bigint types (e.g. Math::GMPz input yields Math::GMPz output).
- Faster GCD on some platforms.
- Peter Dettman supplied a patch for Shawe-Taylor prime generation to
make it deterministically match reference implementations. Thanks!
[Misc]
- Check for old MPFR now using C library version, not module version.
- prime_count_{lower,upper} now uses MPFR to give full precision.
- Montgomery math and uint128_t enabled on Darwin/clang.
0.51 2015-06-21
[ADDED]
- sum_primes(lo,hi) Summation of primes in range
- print_primes(lo,hi[,fd]) Print primes to stdout or fd
- is_catalan_pseudoprime(n) Catalan primality test
- is_frobenius_khashin_pseudoprime(n) Khashin's 2013 Frobenius test
[FUNCTIONALITY AND PERFORMANCE]
- Slightly faster PP sieving using better code from Perlmonks.
- Lucas sequence works with even valued n.
- Used idea from Colin Wright to speed up is_perrin_pseudoprime 5x.
We can check smaller congruent sequences for composites as a prefilter.
- is_frobenius_pseudoprime no longer checks for perfect squares, and
doesn't bail to BPSW if P,Q,D exceed n. This makes it produce some
pseudoprimes it did not before (but ought to have).
[Misc]
- Work with old MPFR (some test failures in older Win32 systems).
- Don't assert in global destructor if a MemFree object is destroyed.
0.50 2015-05-03
[ADDED]
- harmfrac(n) (num,den) of Harmonic number
- harmreal(n) Harmonic number as BigFloat
- sqrtint(n) Integer square root of n
- vecextract(\@arr, mask) Return elements from arr selected by mask
- ramanujan_primes(lo,hi) Ramanujan primes R_n in [lo,hi]
- nth_ramanujan_prime(n) the nth Ramanujan prime R_n
- is_ramanujan_prime(n) 1 if n is a Ramanujan prime, 0 otherwise
[FUNCTIONALITY AND PERFORMANCE]
- Implement single-base hashed M-R for 32-bit inputs, inspired by
Fori禳ek and Jan�ina 2015 as well as last year's tests with
2-base (2^49) and 3-base (2^64) hashed solutions for MPU. Primality
testing is 20-40% faster for this size.
- Small speedups for znlog.
- PP nth_prime on 32-bit fixed for values over 2^32.
[Misc]
- Changes to nth_prime_{lower,upper}. They use the Axler (2013) bounds,
and the XS code will also use inverse prime count bounds for small
values. This gives 2-10x tighter bounds.
- Tighten prime count bounds using Axler, Kotnik, B羹the. Thanks to
Charles R Greathouse IV for pointing me to these.
0.49 2014-11-30
- Make versions the same in all packages.
0.48 2014-11-28
[ADDED]
- lucasu(P, Q, k) U_k for Lucas(P,Q)
- lucasv(P, Q, k) V_k for Lucas(P,Q)
[Misc]
- Use Axler (2014) bounds for prime count where they improve on Dusart.
0.47 2014-11-18
[ADDED]
- is_mersenne_prime(p) returns 1 iff 2^p-1 is prime
[FUNCTIONALITY AND PERFORMANCE]
- Standalone compilation (e.g. factoring without Perl installed) is easier.
- For next_prime and prev_prime with bigints, stay in XS as long as
possible to cut overhead. Up to 1.5x faster.
- Factoring on 64-bit platforms is faster for 32-bit inputs.
- AKS is faster for larger than half-word inputs, especially on 64-bit
machines with gcc's 128-bit types.
- is_provable_prime goes through XS first, so can run *much* faster for
small inputs.
[OTHER]
- NetBSD improperly exports symbols in string.h, including popcount.
Rename our internal function to work around it.
- is_power now takes an optional scalar reference third argument which
will be set to the root if found. It also works for negative n.
- Changes to trim a little memory use. lucas_sequence goes from
PP->[XS,GMP,PP] to XS[->PP[->GMP]]. ecm_factor is moved out of root.
Moved some primality proving logic out of root.
- primes.pl when given one argument will show primes up to that number.
0.46 2014-10-21
[API Changes]
- is_pseudoprime has the same signature as is_strong_pseudoprime now.
This means it requires one or more bases and has no default base.
The documentation had never mentioned the default, so this should
have little impact, and the common signature makes more sense.
[ADDED]
- hammingweight(n) Population count (count binary 1s)
- vecreduce {...} @v Reduce/fold, exactly like List::Util::reduce
[Misc]
- Syntax fix from Salvatore.
- vecmin / vecmax in XS, if overflows UV do via strings to avoid PP.
- Add example for verifying prime gaps, similar to Nicely's cglp4.
- divisor_sum wasn't running XS code for k=0. Refactor PP code,
includes speedup when input is a non-Math::BigInt (e.g. Math::GMP).
- Improve test coverage.
[PP Updates]
- Large speedup for divisors with bigints in 64-100 bit range.
- Revamp RiemannZeta. Fixes some bignum output, but requires RT fixes.
- Optimization for PP comparison to ~0.
- PP factoring is faster, especially for small inputs.
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!
The Zarith library implements arithmetic and logical operations over
arbitrary precision numbers. It uses GMP to efficiently implement
arithmetic over large numbers. Small integers are represented as Caml
unboxed integers for speed and space economy.

2.01080606a
cygwin's tar generated 0-permissions for the distribution (no auto-workaround...).
Document workarounds for isprime() with version 2.1.7 (in the BUGS section).
2.01080607
Correct the documention about fraction of witnesses from >=0.25 to >=0.75.
Define HAS_STAT and HAS_OPENDIR basing on $Config{i_sysstat} and $Config{i_dirent}.

New patch: diff_2.3.5_stderr_clobber
New test: 01_no_extra_newlines.t
Allow download not only via FTP, but also through HTTP.
In presence of PERL5_CPAN_IS_RUNNING, assume that NO ANSWER on prompt is agreement.
(It looks like cygwin and MSWin32 automated-testing environment do not have
AUTOMATED_TESTING and PERL_MM_USE_DEFAULT set...)
Do not auto-download on 64-bit builds of MSWin32.
2.010807
Too long version name was a misprint.
Pay attention to PERL_EXTUTILS_AUTOINSTALL when interpreting empty answers to prompt (probably an overkill).
(disable this abomination by PERL_MATHPARI_TRUST_MANUAL)
(to see why this may be needed: http://www.cpantesters.org/cpan/report/a5d65ec6-6bf3-1014-87a8-67ba45601f20)
Report bytes in the answer for prompt.
Separate into separate subroutines inspecting versions available for download from the actual download.
Change the logic of fallback Net::FTP --> LWP: before, if Net::FTP fails in retrieving the directory listing;
now: if this happens, or if it fails to retrieve the file (how can it happen?! see http://www.cpantesters.org/cpan/report/e7f9d5a7-6bfa-1014-9d0f-1948c9c86cae)
__wrap_PARI_macro: new function (not exported)
parse_as_gp: new function (exported by default)
More verbose error message for "Cannot load a Pari macro".
2.010808
A night of sleep fixed problems of parse_of_gp with the operator \ and empty lines.
(test suite updated)
Actually, mingw was not ready for HAVE_OPENDIR.
Store which patches were applied in $dir/.perl.patches.
Report which patches were not applied.
Export patches_for() from BuildPari.
pari_tgz build option was broken (by LWP-after-NFTP support code which, apparently, did not help with timeouts).
Ignore 0-size "downloaded" files.
The PCG family of Random Number Generators combines properties not
previously seen together in the same generation scheme:
+ It's really easy to use, and yet its very flexible and offers
powerful features (including some that allow you to perform silly
party tricks).
+ It's very fast, and can occupy very little space.
+ It has small code size.
+ It's performance in statistical tests is excellent (see the PCG
paper for full details).
+ It's much less predictable and thus more secure than most generators.
+ It's open source software, with a permissive license (the Apache license).
