Your is_number("-") crashes.
Thank you for the bug report. I'm appreciative for sure. I made a fix and a test. The wiki is updated. I'll look at all your suggestions. In the meantime, this was the stopgap I applied.
-- we'll skip the sign if it has one if find(maybe[i], "+-") then i += 1 end if -- The index might have just moved. Make sure there is at least 1 more character to consider. if i > length(maybe) then -- <<-- New code return 0 end if
