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