        * 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

	  information for math::bignum.

2006-02-21  Arjen Markus  <arjenmarkus@users.sourceforge.net>

	* linalg.tcl (matmul): Fixed [SF Tcllib Bug xxxxxxx]. The bug
	  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

	  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

        * 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.

	  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

        * 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)

        * statistics.tcl/test/man:
          Added several methods: 2x2 tables and two quality
          control charts

        * elliptic.tcl/man:
          Added functions cn, dn and sn. Test cases still
          needed.

	* constants.tcl: Corrected ::math::constants::find_huge
	                 and ::math::constants::find_tiny to not go
			 into an infinite loop when overflow is not an error.
	
2005-05-04  Arjen Markus <arjenmarkus@users.sourceforge.net>

        * Removed reference to argv0 in optimize.tcl (in response
          to a complaint by Bob Techentin)

2005-04-25  Arjen Markus <arjenmarkus@users.sourceforge.net>

        * 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>

          (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)

2005-01-04  Arjen Markus <arjenmarkus@users.sourceforge.net>

        * 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

	  regular run of the SAK tool.

        * Updated the code and expanded test cases

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>

        * Moved initialisation of CDF in statistics module to
          first call

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

	* Released and tagged Tcllib 1.6 ========================
	*

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.

	* 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)

	* fuzzy.test: New files for fuzzy comparisons, documentation and
	  testsuite. Fixed some bugs in them. NOTE: There are failures in
	  the testsuite.

	* 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.

	* math.tcl:
	* misc.tcl:

	* combinatorics.tcl:
	* combinatorics.test: Added a 'combinatorics' module containing
	the Gamma function and several related functions (factorial,
