The code that was here was crap (according to the author) and has been removed.
Arjen Markus We have faced a slightly different problem: two files that should be compared with special care for (floating-point) numbers. The solution was simple in design:
This way you are immune to numbers formatted in different ways: 0.1, +.1, 1.0E-01, +1.00e-001 all spell the same number and you can encounter all of these forms (sometimes you have less than perfect control over the precise format).
Arjen Markus Question: would not this be a nice addition for the fileutil module in Tcllib?
GPS maybe it would...
Arjen Markus If so, it would benefit (in my opinion) from two custom procedures:
Arjen Markus A few thoughts for improving the performance:
This would bring back the number of iterations from O(N^2) to O(NlogN). But perhaps it is not worth the trouble :-)
