2006-09-26  Stephane Arnold <sarnold75@users.sourceforge.net>
        * bigfloat.man : fixed a bug in [math::bigfloat::tostr]
        * bigfloat.tcl : when a number is close to zero,
        * bigfloat.test  it takes the precision into account,
        * bigfloat2.tcl  so instead of getting '0' we get '0.e-4'.
        * bigfloat2.test [math::bigfloat::iszero] is not impacted

	  concerns the possibility of using row vectors. Because I
	  did not think they were possible/practical, I regarded all
	  vectors as column vectors or row vectors whenever suitable.
	  Row vectors are however practical, so I needed to add these
	  cases, at least for [matmul].

2006-02-13  Arjen Markus  <arjenmarkus@users.sourceforge.net>

	* bignum.tcl (rshift): Fixed [SF Tcllib Bug 1098051]. (Solution

2005-11-04  Arjen Markus  <arjenmarkus@users.sourceforge.net>

        * roman.test: removed extraneous messages

2005-10-26  Arjen Markus  <arjenmarkus@users.sourceforge.net>

        * qcomplex.tcl: error in the computation of the complex
                        cosine. Found by Oscar Andreas Lopez.

2005-10-21  Andreas Kupries <andreask@activestate.com>

	* interpolate.test: Reduced requirement for struct down to
	* interpolate.tcl:  struct::matrix, as that is the only structure
	  used by this package. This means that we are loading 272 KB less

2005-09-09  Stephane Arnold <sarnold75@users.sourceforge.net>

	* bigfloat.tcl : went back to the old algorithm to compute Pi
	  after having done much benchmarks

2005-09-06  Stephane Arnold <sarnold75@users.sourceforge.net>

	* bigfloat.tcl : new and faster algorithm to compute Pi

2005-08-31  Stephane Arnold <sarnold75@users.sourceforge.net>

	* bigfloat.tcl : added many comments and fixed some minor bugs
	  (possibly following to inexact last digits)
	* bigfloat.test : fixed a bug that causes the version number
	  of some tests to be replaced by 1.0 or by the string "version"

2005-08-30  Andreas Kupries <andreask@activestate.com>

	* bignum.tcl: Fixed code exporting the bignum commands, it was
	  done in the wrong namespace. This fixes [Tcllib SF Bug 1276680].

2005-08-29  Kevin Kenny  <kennykb@acm.org>

	* combinatorics.test (combinatorics-2.7,3.10): Revised a few test cases

2005-08-29  Arjen Markus  <arjenmarkus@users.sourceforge.net>

        * Fixed bug #1272910: due to the different rounding
          of 0.5 in Tcl 8.5, the Quantiles-1.0 test failed.
          Using different levels steers the test away from
          this odd edge case.

2005-08-29  Stephane Arnold <sarnold75@users.sourceforge.net>

	* bigfloat.tcl : added comments to make code easier to understand

2005-08-28  Stephane Arnold <sarnold75@users.sourceforge.net>

          command and all kind of constants (mainly integer)
	* bigfloat.test : updated test labels to more significant labels
	* Bug #1272836 : the math round() function has changed
	  in Tcl 8.5a4 (intentionally) - now the round tests
	  do no more rely upon this function.

2005-08-26  Stephane Arnold <sarnold75@users.sourceforge.net>

	* Feature Request 1261101 : automatically convert
	  the strings "0" and "1" to bignums

        * Updated the test file and man page for this
        * Updated the pkgIndex.tcl file (optimize now at 1.0)

2005-08-05  Stephane Arnold <sarnold75@users.sourceforge.net>

	* bigfloat.tcl : Fixed a bug in [fromstr] when a number
	  began with '+' ; another bug, in [fromdouble], when
	  a number began with '+' or '-'.
	* bigfloat.test : Added tests for fromdouble.

2005-08-04  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* bigfloat.man: Replaced a number of ?...? occurences to markup
	  optional arguments with the more correct [opt ...].

2005-08-04  Stephane Arnold <sarnold75@users.sourceforge.net>

	  with an exponent beginning by 0 was given (like 1.1e+099)

	* bigfloat : Added a [fromdouble] new proc.

2005-08-01  Arjen Markus  <arjenmarkus@users.sourceforge.net>

        * Changed the credits for Ed Hume at his request
          (anti-spam measure)

2005-07-26  Stephane Arnold

	* Changed in many places : '[pi $precision]'
	  to '[pi $precision 1]' in which $precision is treated
	  as binary digit length (instead of decimals)
	  since the internal representation of the mantissa is binary
	
2005-07-01  Stephane Arnold <sarnold75@users.sourceforge.net>

	* bigfloat.man,bigfloat.test,bigfloat.tcl : updated

        * Corrected documentation of math::product (was math::prod)

2005-03-16  Andreas Kupries <andreask@activestate.com>

	* bigfloat.tcl: Added package require math::bignum. If we use the
	  package we should load it as well.

	* rational_funcs.tcl: Redone entry '2004-11-22 Andreas Kupries
	  <andreask@activestate.com>'. Somehow the source command came
	  back.

2005-03-11  Arjen Markus <arjenmarkus@users.sourceforge.net>

        * Corrected problem with exponential_Ei - doubly defined

2005-01-14  Arjen Markus <arjenmarkus@users.sourceforge.net>

        * Added version 1.0 of Stephane Arnold's bigfloat package
          (newer versions will come later on)

2005-01-10  Andreas Kupries <andreask@activestate.com>

	* bignum.tcl:  Integrated [Tcllib SF Bug 1093414]. Basic bit
	* bignum.test: operations (and, or, xor) on big numbers. Correct
	* bignum.man:  operation is limited to positive numbers (including
	  zero). The basic code was provided by Aamer Aakther
	  <aakther@users.sourceforge.net>, modifications of docs, and
	  small testsuite by myself.

2005-01-05  Arjen Markus <arjenmarkus@users.sourceforge.net>

        * Added tests for matmul (and corrected the implementation)

        * Expanded the documentation (it should now describe all
          public procedures)
        * Expanded the tests (not complete, but it should cover most
          more complicated procedures)
        * Expanded the set of procedures (only a few algorithms
          await implementation)

2005-01-03  Arjen Markus <arjenmarkus@users.sourceforge.net>

        * Added modified Gram-Schmidt method to the linear algebra package

2004-11-22  Andreas Kupries <andreask@activestate.com>

	* rational_funcs.tcl: Removed bad source'ing of file
	  polynomials.tcl. Depended on current working directory in the
	  right place, and superfluous as well, as immediately after a
	  'package require' of the package loaded it in the proper
	  manner. Disabled the test code at the end as well.

2004-11-08  Arjen Markus  <arjenmarkus@users.sourceforge.net>

        * Added preliminary versions of a linear algebra module
          (revision of Hume's LA). No documentation yet
        * Removed the initialisation of CDF (that was left in there)

2004-11-01  Arjen Markus  <arjenmarkus@users.sourceforge.net>

2004-07-07  Arjen Markus  <arjenmarkus@users.sourceforge.net>

	* bessel,tcl:		Indentation adjusted to conform to
	* bessel.test:		the _Tcl Style Guide._  Errors
	* constants.test:	corrected in the documentation of
	* elliptic.tcl:		Romberg integration.
	* elliptic.text:
	* qcomplex.tcl:
	* romberg.man:
	* special.test:
	
2004-07-05  Kevin Kenny  <kennykb@acm.org>

	* calculus.man:	 		Added Romberg integration to
	* romberg.man:			the library.  The procedures should
	* calculus.tcl (romberg*):	provide a "production quality"
	* calculus.test (romberg-*):	library for integrating functions
	* math.tcl:			of one variable, including functions
	* misc.tcl (expectInteger):	that have integrable singularities
					and integrals over half-infinite
					intervals.
	* constants.tcl:  Changes so that constants get defined in the
	* constants.test: correct namespace. Changed tests so that they
	* elliptic.test:  don't fail when other tests have already run.
	* special.tcl:    Changed the definition of Gamma to the correct
	* special.test:   one.
	Also added copyright notices and CVS IDs in several files that
	lacked them, and corrected indentation in several files.
	
2004-06-19  Kevin Kenny  <kennykb@acm.org>

	* interpolate.man:  Added polynomial interpolation with Neville's
	* interpolate.tcl:  algorithm; this procedure will be needed in
	* interpolate.test: Romberg integration, which is the next project.
	
2004-06-18  Kevin Kenny  <kennykb@acm.org>

	* bessel.test:        Fixed several problems that were causing tests
	* combinatorics.test: to fail or to run noisily. Corrected inconsistent
	* interpolate.tcl:    package version number in interpolate.tcl.
	* interpolate.test:
	* qcomplex.test:

	* optimize.man:   Added min_bound_1d and min_unbound_1d functions
	* optimize.tcl:   to do one-dimensional function minimization,
	* optimize.test:  constrained and unconstrained, respectively,
	                  without derivatives.
	
2004-06-16  Andreas Kupries  <andreask@activestate.com>

	* interpolate.man: Added a missing list_end before section
	  examples. Fixed usage of braces in the example as well.

2004-02-09  Jeff Hobbs  <jeffh@ActiveState.com>

	* combinatorics.tcl (::math::factorial): correct fac 171
	off-by-one and use of -strict in string is int|double.

2003-12-22  Joe English  <jenglish@users.sourceforge.net>
	* calculus.man (rungeKuttaStep): Add missing argument
	in function synopsis (bug report from Richard Body).

2003-10-29  Arjen Markus <arjenmarkus@users.sourceforge.net>

	* statistics.tcl (BasicStat): Applied fix for [SF Tcllib Bug
	  820807]. Uniform data may cause a small negative value when
	  computing the base value for a standard deviation, instead of
	  the correct 0.0. The fix now enforces 0.0 when encountering this
	  situation. This entry in the ChangeLog by Andreas Kupries.

2003-04-24  Andreas Kupries  <andreask@activestate.com>

	* pkgIndex.tcl: Found math::optimize missing in index.
	* optimize.man: Version number inconsistent with code,
	  corrected.

	* calculus.test: Converted [puts] into log statements, and
	  suppress them by default. Reduces the noise when running the
	  testsuite.

	* statistics.test:    package we are testing.
	* calculus.test:
	* geometry.test:

	* optimize.test:

2003-04-24  Arjen Markus <arjenmarkus@users.sourceforge.net>

	* liststat.tcl: Corrected the handling of the expression in the
	  list manipulation procedures. This solves the scope problem (bug
	  725231). AK: Lifted from the 'cvs log'. This passes the testsuite.

2003-04-23  Andreas Kupries  <andreask@activestate.com>

	* fuzzy.test: Re-applied bug fixes I did before (See 2003-04-13)
	  to the newly committed version, which was not merged, but simply
	  overwrote my changes.

2003-04-21  Andreas Kupries  <andreask@activestate.com>

	* optimize.test: Corrected errors in loading the functionality
	  under test, and of accessing tcltest. Now functional.

2003-04-18  Joe English  <jenglish@flightlab.com

	* optimize.man: fix minor markup errors that doctools and tmml
	  were complaining about.

2003-04-16  Andreas Kupries  <andreask@activestate.com>

	* pkgIndex.tcl: Added math::statistics after yesterday's commit by
	  Arjen Markus.

	* statistics.test: Changed to conform to standard of importing
	  tcltest, changed import of tested functionality, added checks
	  that actually tcltest 1.2 or higher is used (Aborting if not).
	
	* statistics.tcl:
	* liststat.tcl
	* pdf_stat.tcl:
	* plotstat.tcl: Reformatted a bit to be more near to the
	  style-guide with regard to indentation.

	command name.
	* misc.tcl: removed [package provide math]; duplicated in
	math.tcl, a sync problem waiting to happen.

2002-01-18  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* Bumped version to 1.2.

2002-01-18  Andreas Kupries <andreas_kupries@users.sourceforge.net>

	* Added calculus functionality and fuzzy FP comparison as provided
	  by Arjen Markus <arjen.markus@wldelft.nl> as is. This code
	  currently has neither true testsuite nor good documentation but
	  was considered important enough to get in now. Polish has to
	  come in the subsequent patch releases.

2002-01-11  Kevin Kenny  <kennykb@users.sourceforge.net>

	* combinatorics.tcl: Removed incorrect 'package provide'.

	* math.tcl:
	* misc.tcl:
	* pkgIndex.tcl:
	* tclIndex: Reorganized so that math.tcl is a top-level 'package
	provide' script and loads a tclIndex.  The code from 'math.tcl'
	moves into 'misc.tcl'.
	* combinatorics.n:
	* combinatorics.tcl:
	* combinatorics.test: Added a 'combinatorics' module containing
	the Gamma function and several related functions (factorial,
	binomial coefficient, and Beta). (Feature request #484850).
