I have a large text file containing sentences, paragraphs, etc. I need a script that scans through the text file and create an array of only the numbers contained in the text file.

List the exact set of formats that numbers might occur in.
For example, is .E+30 a valid number for your purposes? If you permit 0.E+30 and you permit .0E+30 then is .E+30 also permitted? Are the + always omitted but - are used, so 0.E30 and 0.E-30 would be permitted but not +0.E30 or 0.E+30 ? Can 'e' be used instead of 'E' ? Can 'D' be used instead of 'E' ? Can there be complex numbers? If there is an integer, is it permitted for it to be followed by '.', so 12345. ? Or is '.' always followed by a digit?
