First understand that RegEx is pretty much just string searching/pattern searching, and if there are a lot of "matches" it goes pretty slow. Second, try to define the true scope of the problem by considering how many lines of data would be scanned at one time, does the user have to wait while this is accomplished, are there smarter ways of using 'replace' 'filter' etc. Questions: 1-- How many number are you processing (10, 10K, 100K)? 2-- Are the "+" and "-" signs present as you indicate? 3-- Would sort ascending, scan, then sort descending, scan >> find the key lines to then 'get line topp to bott of numberList 4-- Is math necessary, or could the simple string be analyzed to do a coarse cut, then use a repeat to refine the smaller list a both ends? 5-- What does "-067.145780" stand for, since this would indeed be a string and not a real number with the leading 0. My first glance would try to sort, snip, sort, snip, refine with [math/filter/regex/replace].
