2012-02-01  Zefram  <zefram@fysh.org>

	* Don't declare "tan" operator overloading on Math::Complex
	  objects, because there is no such overloading type [rt.cpan.org

	* Remove execute bit from test scripts in CPAN tarball.

	* Release Math::Complex 1.59 + Math::Trig 1.23.

2011-06-21  Zefram  <zefram@fysh.org>

	* Declare package variables with "our" rather than "use vars".

	* Corresponding to "our" usage, check for minimum Perl version

	* Remove $ENV{PERL_CORE} logic from test suite, which is no
	  longer desired in the core.

	* In test suite, remove obsolete and now-incomplete handling of
	  unavailability of Test::More.

	* Declare module dependencies.

	* Release Math::Complex 1.58 + Math::Trig 1.22.

	* Add copy constructor and arrange for it to be called
	  appropriately, problem found by David Madore and Alexandr

	* Correctly format polarwise when a numeric format specifier is

2009-02-08  Jarkko Hietaniemi  <jhi@iki.fi>

	* Fix qw(abs cos exp log sin sqrt) without argument, problem
	  found by Steffen Mueller, 5.10-aware (lexical $_) fix by Abigail.
	* Release Math::Complex 1.56 + Math::Trig 1.20.
2008-12-27  Jarkko Hietaniemi  <jhi@iki.fi>

	* Resolve rt.cpan.org report: 
	  "#39045: great_circle_direction gives wrong answer if 5th argument is supplied"
	  by calling great_circle_distance() with an explicit argument
	  list in great_circle_direction().
	* Release Math::Complex 1.55 + Math::Trig 1.19.
2008-04-04  Jarkko Hietaniemi  <jhi@iki.fi>

	* The SIGFPE catcher in Complex.pm and Trig.t was { }, not sub { }.

	* Shuffle the Inf-guessing guesses a bit to try infinities first,
	  and also 2**99999 before exp(99999), seems to be more reliable
	  for generating the infinity for some odd reason (the ** is
	  implemented via exp() anyway?)
	* In cosh() and sinh() more robustly produce Inf() when needed,
	  even when exp() seems to "stick" into DBL_MAX and not go to Inf.
	* Release Math::Complex 1.54 + Math::Trig 1.18.
2008-04-01  Jarkko Hietaniemi  <jhi@iki.fi>

	* Resolved rt.cpan.org report:
	  "#34605: Math::Trig(3pm) man page feedback"
	  (Trig.pm talked of "arcus hyperbolic sine", which is wrong,
	   it is either "area hyperbolic sine" or "inverse hyperbolic sine")

	* Tweaked also the code comments a bit to speak consistently of
	  "area/inverse hyperbolic ..."

	* Resolved rt.cpan.org report:
	  "#34269: Math::Trig::great_circle_destination"
	  (One cannot combine the results great_circle_distance(A, B) and
	   great_circle_direction(A, B) to get great_circle_destination(A, ...)
	   to return B, because the bearing keeps changing in the general case)
	* Release Math::Complex 1.53 + Math::Trig 1.17.
2008-02-11  Jarkko Hietaniemi  <jhi@iki.fi>

	* Duh. Forgot 128-bit option from the %DBL_MAX table.

2008-02-10  Jarkko Hietaniemi  <jhi@iki.fi>

	* Make the nv max detection to work also with
	  long doubles, reported by Nicholas Clark
	  [core perl change #33268]

	* Release Math::Complex 1.51 + Math::Trig 1.15.
	  (1.50 skipped because of "1.5" idiocy.)
2008-04-04  Jarkko Hietaniemi  <jhi@iki.fi>

	* The debugging output in Complex.pm BEGIN was not nice:
	  remove that, resolving rt.cpan.org #32919.

	* Make the detecting of Infinity even more relaxed:
	  just be happy with defined() and "big enough".
	  (Switch the '1e999' as last resort, though.)
	* Release Math::Complex 1.49 + Math::Trig 1.14.
2008-01-29  Jarkko Hietaniemi  <jhi@iki.fi>

	* In HP-UX the infinity is stringified as "++" and
	  the negative infinity as "--", fix from H. Merijn Brand.

2008-01-16  Jarkko Hietaniemi  <jhi@iki.fi>

	* The great circle tests with small angles didn't work
	  with long doubles in Mac OS X, reported by conrad.
	  Oh, the joy of floating point.  Fudged the test hopefully enough.
	  Could special case going from point A to point A,
	  but that would be cheating.  (For really small movements
	  could also just do Pythagorean plane distance.)
	* Release Math::Complex 1.47 + Math::Trig 1.12.
2008-01-16  Jarkko Hietaniemi  <jhi@iki.fi>

	* Fix a typo in the asin_real/acos_real documentation
	  noticed by Alexej Sveshnikov.

2008-01-15  Jarkko Hietaniemi  <jhi@iki.fi>

	* Address [rt.cpan.org #32291] Wrong (Math::Complex) results in great_circle family of functions
	  Fix gratefully received from the reporter of the bug,
	  Alexej Sveshnikov.

	* Added the two new interfaces added by the fix for the
	  rt.cpan.org #32291, asin_real() and acos_real(), also
	  to the public interface.
	* Release Math::Complex 1.45 + Math::Trig 1.10.
2008-01-11  Jarkko Hietaniemi  <jhi@iki.fi>

	* Address rt.cpan.org #27186: Shadowed By the Core Version
	  by adding INSTALLDIRS => 'perl' to Makefile.PL.
	* Ignore SIGFPE in Trig.t when doing arithmetics with
	  infinities (avoids a coredump in netbsd-alpha, found
	  by David Cantrell).  Document this fun.

	* Make Math::Complex and Math::Trig documentations to
	  refer to each other.
	* Release Math::Complex 1.44 + Math::Trig 1.09.
2008-01-09  Jarkko Hietaniemi  <jhi@iki.fi>

	* sinh(1e4) was not enough to go to infinity in AMD64
	  with long doubles (sinh(1e5) was), and test.pl:is()
	  didn't work for infinities (subtle overloading issue.)
	  Fix from Nicholas Clark.
	* Release Math::Complex 1.43 + Math::Trig 1.08.
2008-01-07  Jarkko Hietaniemi  <jhi@iki.fi>

	* The infinity detection was wrong for Microsoft libc,
	  there infinity is '1.#INF'.  Now made the detection
	  hopefully much more robust.
	* Release Math::Complex 1.42 + Math::Trig 1.07.
2008-01-06  Jarkko Hietaniemi  <jhi@iki.fi>

	* PAUSE upload had some issues which messed up 1.39 upload,
	  reissue after reviewing (and fixing) the diffs.
	* Release Math::Complex 1.41 (1.40 skipped because
	  of silly "1.4.tar.gz" feature) + Math::Trig 1.07.
	  [deleted from CPAN because broken in Win32]
2008-01-06  Jarkko Hietaniemi  <jhi@iki.fi>

	* Add the standard "same terms as Perl itself" license
	  to both Complex.pm and Trig.pm.

	* Add Inf() as an exportable sub, it returns the infinity
	  (or the best floating double imitation of it).

	* Make the BEGIN block of Complex.pm croak if it cannot
	  find an infinity.  This may be deadly on some platforms
	  but then again, Complex.pm has returned infinities for
	  quite some time now.
	* tanh(a big enough number) was returning NaN in Unix and 1+NaN
	  in Windows when the right answer is 1 (for IEEE doubles
	  the limit seemed to be 709 vs 710).  Added tests for
	  sinh/cosh/tanh/sech/csch for 100/-100, and for sinh/cosh
	  with 1e4 returning Inf().  Reported by Roberto Congiu.

	* Added sanity check tests to Trig.t for all the trigonometric
	  and hyperbolic functions (staying in real axis, not going to
	  complex plane).
	* Release Math::Complex 1.39 + Math::Trig 1.06.
	  [deleted from CPAN because of PAUSE upload problems]
2007-12-30  Jarkko Hietaniemi  <jhi@iki.fi>

	* The example for great_circle_waypoint() had latitude and
	  longitude switched; reported by Chris Heys.
	* Cosmetic changes in test files.
	* Release Math::Complex 1.38 + Math::Trig 1.05.
2007-01-21  Jarkko Hietaniemi  <jhi@iki.fi>

	* great_circle_waypoint() was broken (the latitudes
	  were garbage); report and fix by Uwe Girlich.
	* local()ize $! in the BEGIN block when looking for Inf.
	* Release Math::Complex 1.37.
2006-07-04  Jarkko Hietaniemi  <jhi@iki.fi>

	* Move the pi-constants from Math::Trig to Math::Complex.

	* Hide some of the internal-use-only functions/methods
	  by prepending an underscore to the names.

	* Update Dan Lewart's email address.
	* Introduce pod.t and pod-coverage.t; make the tests
	  to be correctly skipped if Test::More or Test::Pod::Coverage
	  are not available.

	* Tiny doc tweaks.

	* Add a TODO file.
	* Grab the Math::Complex and Math::Trig changes from
	  the Perl 5 Perforce repository (see below).
	* CPAN release Math::Complex 1.36 + Math::Trig 1.04. 
Changes below this are changes of the Perl 5 Perforce repository
that somehow touched Math::Complex, Math::Trig, and/or their tests.	
They brought Math::Complex to 1.35 and Math::Trig to 1.03,
after which Math::Complex and Math::Trig were CPANized as 1.36 and 1.04.

	The Grand Trek: move the *.t files from t/ to lib/ and ext/.
	No doubt I made some mistakes like missed some files or
	misnamed some files.  The naming rules were more or less:
	(1) if the module is from CPAN, follows its ways, be it
	    t/*.t or test.pl.
	(2) otherwise if there are multiple tests for a module
	    put them in a t/
	(3) otherwise if there's only one test put it in Module.t
	(4) helper files go to module/ (locale, strict, warnings)
	(5) use longer filenames now that we can (but e.g. the
	    compat-0.6.t and the Text::Balanced test files still
	    were renamed to be more civil against the 8.3 people)
	installperl was updated appropriately not to install the
	*.t files or the help files from under lib.
	TODO: some helper files still remain under t/ that could
	follow their 'masters'.	 UPDATE: On second thoughts, why
	should they.  They can continue to live under t/lib, and
	in fact the locale/strict/warnings helpers that were moved
	could be moved back.  This way the amount of non-installable
	stuff under lib/ stays smaller.
