Hi Ryan,

I AM interested,  and it's a great idea.  Real Ruby rather than my C-
flavored Ruby :-)

Just for our mutual amusement,  I replaced your first criterion:

err1 = inp.select{|a| a =~ /^0|\.0/}

with:

err1 = inp.select{|a| a =~ /^0|^\d*\.0/}

to preclude false hits where the text proper might contain ".0", e.g.,
"7How to get 5.05% interest"

Bottom line:  Your code is what I really need.  Thanks, again.

Best wishes,
Richard
