Revision history for Math-Utils
1.14
        10 Apr 2020
        - Add the function softmax(). Currently in the :utility tag
          group, which may be too generic. We'll see what else gets
          added later and adjust the tagging then.
        - New functions uniform_scaling(), and uniform_01scaling(),
          contributed by Gene Boggs (GENE).
        - Typo found by Miguel Prz (NICEPERL) fixed.
1.13
        30 Oct 2018
        - Add function pl_translate(), by request.
        - Turn README into README.md. With MetaCPAN replacing CPAN,
          there is no reason to have a plain-text README anymore
          (MetaCPAN doesn't treat the file as special).
        - Add a CONTRIBUTING.md file, which is becoming a thing.
        - New test file for pl_translate(), and upgrade test files
          that for some reason were still using Test::Simple to Test::More.
        - Added an :all tag. Why not.
1.12
        26 Jun 2018
        - Typo found by Florian Schlichting fixed.
        - Add gcd() and lcm() functions.
        - New example scripts (a couple transferred over from
          Math::Polynomial::Solve) in the new eg/ directory.
1.11
        11 Aug 2017
        - Stupidly depended on Module::Start's boilerplate text for the
          license, which points to a differently worded license text
          from what I've got in the LICENSE file. Changed that.
1.10
        10 May 2017
        - Extended pl_evaluate() to allow lists of values for the X terms.
          Lists may be of values or of ARRAY refs.
        - Added tests in 16-evaluate.t for the list cases.
1.09
        11 May 2016
        - New function fsum(), using Kahan's summation algorithm.
        - Added tests in 17-derivative-eval.t to check for the
          linear polynomial and the constant-only polynomial.
          (They passed, but until now those cases hadn't been tested.)
        - Extend the documentation for pl_div(), emphasizing the
          need to remove leading zeros.
1.08
        24 Feb 2016
        - Inlined the comparison functions of generate_relational().
        - Default tolerance was just under square root of (an) epsilon,
          changed to to just over.
        - Updated 01-compare.t to test edge cases.
        - Added a log2() function, because why not.
1.07
        23 Nov 2015
        - Search using grep.cpan.me indicated that floor() and ceil()
          functions weren't defined in general-purpose modules (and
          the modules they were in were pretty heavy-weight). Decided
          to add them to the module.
        - Repeated modulus of a number was worth making into
          utility function moduli().
1.06
        7 Oct 2015
        - The if statements were laid out in generate_fltcmp in
          a way that could return a -1 (less than) when the two
          values were actually equal within tolerance. Changed this.
        - Renamed some test files so that the compare test comes
          first.
1.05
        25 Sep 2015
        - Bug in pl_derivative() for linear equation case.
        - Added test cases to cover it.
1.04
        20 Sep 2015
        - I had bumped the version number everywhere but in the module
          itself. This will probably complicate something, so
          fix this everywhere with a version 1.04.
        - Add a flipsign() function to the :utility list.
        - More documention clean-up. Mention Math::VecStat
          in the SEE ALSO.
1.03
        18 Sep 2015
        - Put :fortran tagged functions copysign() and log10()
          in the :utility tagging. The :fortran tag sticks around
          though.
        - New function pl_dxevaluate() for returning the y, dy,
          d2y values of the polynomial at x.
        - New test files for pl_evaluate() and pl_dxevaluate().
1.02
        15 Sep 2015
        - Documentation error in pl_div() (mis-named variables
          in the example).
        - Extended the SEE ALSO paragraph.
        - Very minor code clean-up in pl_antiderivative().
1.01
        5 Sep 2015
        - I had left test file 15-objcoeff.t off the MANIFEST list. Oops.
        - Embarrassing number of grammatical and spelling errors fixed.
        - Clarified a couple of examples, and extended the
          pl_antiderivative() documentation with respect to the
          constant term.
        - Version bump; up to CPAN.
1.00
        3 Sep 2015
        - Added the coefficient list functions for addition, subtraction,
          division, multiplication, derivative, antiderivative,
          and evaluation (via Horner's method) of polynomials without
          actually creating a polynomial object.
        - Added the tests for the above operations.
0.02
        30 Aug 2015
        - CPAN testers caught a 5.10ism in the module, which is
          listed as okay for version 5.8. Decided to bump the
          minimum version requirement to 5.10.1.
        - Documentation was sketchy, so added more descriptive
          text and examples.
        - Version bump; up to CPAN.
0.01
        18 Aug 2015
        - Collection of utility functions for Math modules, starting
          with the functions of Math-Fortran as a base.
