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 X XWWW: http://www.math.utah.edu/~beebe/software/ndiff/ X XHave fun.
