ndiff is a utility for comparing putatively similar files, ignoring small
numeric differences. The utility is written by Nelson H. F. Beebe and
covered by the GNU General Public License (GPL), version 2. It may be
built with arbitrary precision support (more powerful) or using built-in
floating point precision, see Makefile.
Assessing the consistency of a numerical program run in multiple
environments (operating systems, architectures, or compilers) can be a
difficult task for a human, as small differences in numerical output values
are expected. File differencing utilites, such as diff(1), will generally
produce voluminous output, often longer than the original files.
ndiff solves this problem. Taking two two text files expected to be
identical, or at least numerically similar, it allows to specify absolute
and/or relative error tolerances for differences between numerical values
in the two files, and then reports only the lines with values exceeding
those tolerances. It also tells by how much they differ. A simple example:
% ndiff --relative-error 1.0e-3 test019.txt.1 test019.txt.2
### Maximum relative error in matching lines = 8.64e-51 at line 129 field 4

distfile (which must be manually downloaded) into one that is
compatible with bento builds. This should be transparent to
anyone installing the port. Informed maintainer.

Important changes:
==================
- Kmail and knode have been moved from kdenetwork to kdepim. This
means you will have to install kdepim if you want to continue using
kmail or knode. This is to ease integration with korganizer, in
the new 'Kontact' application.
- The arabic translations for KDE and KOffice have been moved from
misc to the arabic category.
- There is a new module called kdeaccessibility in the accessibility
category. It contains a few utilities for disabled users like a
magnification lens and a text-to-speech frontend.
- In KDM, you need to select the 'CUSTOM' session profile in order
to have your .xsession executed. This is particularly important if
you're using the aegypten tools
(http://freebsd.kde.org/howtos/aegypten-kmail.php).
- We have started making more parts of the ports optional. In kdepim,
both Kandy and KPilot can be turned off with ports-knobs. This
process will continue in the 3.2 series.
