It appears to me you've taken my comment followup as a literal question rather than what I meant which is why would sv_2nv convert "aa" to a 0 double and how may I avoid this but still have it work for real numbers.

I would like the code above to convert the sv to a double when that is reasonable and not otherwise and I'd like to know when it cannot do it.
