- 2010-01-24: New version 5.2.1 . Changelog:
- Corrected a bug which prevented Numdiff to be built on MacOS X(R)
without Natural Language Support.
Thanks to Antoine Dechaume for the report.
- 2010-01-07: New version 5.2.0 . Changelog:
- Numdiff uses now the GNU Multiple Precision Arithmetic Library
(also called GNU MP or GMP) if this library is available
The old internal support for multiple precision arithmetic is deprecated,
since Numdiff is quicker if linked against GMP.
After building and installing Numdiff,
you can know whether it has been
linked against GNU MP or not just by calling the program
with the option
See the User Manual for additional information.
- 2009-11-31: New version 5.0.0 . Changelog:
- The filter embedded in Numdiff has been improved,
it gets no more confused if the same value is
represented in scientific notation in one file
and in ordinary decimal notation in the other file.
- The Makefile.in (and consequently the Makefile) has
been modified to conform to the GNU Coding Standards.
- Now numdiff and ndselect accept long options too
--separator='\n\t %' instead of
-s '\n\t %').
- The option
-r accepts now an additional parameter
which tells to compute the relative differences always with
respect to the values in one file, instead of using
the classic formula for the relative error.
- The argument of the option
-f has been made optional.
- Documentation, i18n and italian l10n have been updated.
- 2009-08-07: New version 5.0.0-beta4 . Changelog:
ndfilter has been removed. A much better filtering mechanism, which
can be triggered and tuned through suitable command line options,
is now included in Numdiff.
- The output format has been slightly modified to let it work
well together with the filter.
- The option
-L has been removed, since
ndselect made it obsolete.
- The option
-F has been replaced by
however differently, see the User Manual for details.
- The output of the option
-S has been improved with addition of
new useful information.
- The option
-s has now an extended syntax allowing to specify
different sets of field delimiters for the two files to compare.
- Support for double-, long double- and high-precision arithmetic has been
dropped, since multiple-precision arithmetic is better and fast enough.
- Test routines are not anymore distributed together with
the source code of Numdiff.
- Adoption for the source code of the GNU General Public
License version 3 (or later) and for the User Manual
of the version 1.3 (or later) of the GNU Free Documentation License.
- Copyright has been updated but i18n and Italian l10n are
- 2007-05-21: New version 4.2.0 . Changelog:
- Changed the way the options
interact when they are both set.
- Added the tools
ndselect together with new tests.
See the section Tools of the User Manual to know
what you can do with
- Now, when the options
-h are both set,
Numdiff displays before the information about version,
Copyright and NO-Warranty and then the help message.
- Copyright, i18n and Italian l10n updated.
- 2006-11-20: New version 4.0.0 . Changelog:
- New output format. See the section Warnings of the
User Manual for a detailed list of all the changes with
respect to the version 3.0.x. At the same time the code printing the output
has been cleaned.
- Added the verbose mode (
- Better handling of the last line of a file.
- i18n, l10n and documentation have been consequently updated.
- 2006-03-23: New version 3.0.2 . Changelog:
- Fixed a compilation error which occurred when one
chose to activate the double, the long-double or the high
precision instead of the multiple precision arithmetic.
This compilation error was introduced just before releasing
the version 3.0 of Numdiff .
- The code for the computation of the absolute value of a complex number
in double and long double precision has been improved.
- 2006-03-22: New version 3.0.1
The only change with respect to the previous version 3.0
has been made in order to speed up the execution of the
program when built with the support for multiple precision
- 2006-03-20: Numdiff 3.0 is finally ready !
