Revision history for Perl extension Math::Fraction.
.1a (1 March 1997) Original Release
.2a (2 March 1997) Many Internal Changes:
Fixed reduce method so it no longer needs a list of primes after
discovering a method in the BigInt module
Modified + and * routines to work with as small numbers of possible
after reading the fraction section of Knuth's "The Art of Computer
Programming" v2 book that I checked out thanks to the reference
in the BigInt module
Modified - and / routines to with take the negative or receptacle
of the second fraction and then use the + and - method respectively
(And when I was browsing the list I also discovered bigrat.pl, but
not a BigRat.pm. Oh well I guess I reinvent the real a bit but
I think I created a better one. I plan to eventually have it is
the BigInt package to work with arbitrary size fractions.)
Changed the behavior of the MIXED method slightly so that it will
display "8/9" instead of "0 8/9"
Fixed it so that all the internal functions calls will return list
instead of fraction objects, simplifies things internally
Created a separate internal reduce function that the reduce method
calls and created a separate internal function to simplify signs.
Also fixed it so all new fractions will automatically have their signs
simplified (ie 1/-2 will become -1/2 and -1/-2 will become 1/2);
And probably a few more that I forgot to mention.
.21a (3 March 97) Fixed the strange decimal conversion behavior.
.211a (3 Match 97) Fixed % by zero bug
.22a (3 March 97) Added demo a demo subroutine to the test script.
.3a (8 March 97) First Version to be Uploaded to CPAN.
Renamed to Math::Fraction
Added Default tags
Added Using arbitrary sized numbers.
.4a (24 March 97)
Changed the structure of a Fraction object to now have a 'frac' part and a
'tags' part.
Fixed the _from_decimal sub to work properly recognize large repeating
floats properly.
Added support for default sets so that functions can have the own private
set of default values.
Added a new AUTO which when set will convert the fraction from SMALL
to BIG as needed.
Fixed the modify_tag so that it will convert the fraction to reflect the
new tags.
And a lot of other minor bugs fixed.
.5b (17 Dec 97)
Changed from an Alpha release to a Beta release because I have not herd of
any problems yet.
Converted the Manual into POD format
Fixed the module so it has a proper install procedure.
Modified the copyright a bit to be less intimidating.
Changed the Demo Script a bit so it would display better in the manual page.
.51b (18 Dec 97)
Fixed bug in which the whole number part of repeating decimals was ignored
.52b
Fixed error in the EXAMPLES section of the manual due to the fixing of the
repeating decimal error
Added the RAW tag which will always include the sign
Minor corrections to the manual
.53b (2 Feb 98)
Fixed a bug where negative mixed fractions will come out as -1 -1/4
instead of -1 1/4.
Fixed a bug so that frac(0,MIXED) will return 0 and not a 0 length string.
