Compare similar files with numeric fields
Numdiff is a console application that can be used to compare putatively
similar files line by line and field by field, ignoring small numeric
differences or/and different numeric formats. It is similar diff or wdiff,
but it is aware of floating point numbers including complex and
multi-precision numbers.
Numdiff is useful to compare text files containing numerical fields, when
testing or doing quality control in scientific computing or in numerical
analysis.
