So you define "leading digit carry operation" here, it is not something in 
geneal knowledge?

Please keep from using your private terminology without initializing it 
properly.

Ofcourse you cannot add 1 to a nonexisting value,
so that is not a problem, but univeral mathemeatical logic.

Expecting a nonexisting value to be zero or whatever is ludicrous.

You should be glad that Javascript does not crash or error out,
but gives you the NaN-value, but it stays bad programming.

====================

Long gone are the days that
"All numerical variable are created zero"
and 
"All people are created equal".

The first is untrue because Old Style BASIC is no more,
the second is untrue because people are not created.
