You mean that the first string to be converted to binary would
automatically set the decimal separator? That would seem dangerous to me.
What if the first string to be converted contained something like "11,000",
does this mean 11000 with thousand separator = comma (which would be true
in at least USA), or 11 with decimal separator = comma (which would be
true at least in France)? I can't think of any way to choose automatically.
AFAICS, the code needs either to use the system settings or to be told
explicitly by the developer. Even relying on the system settings may not be
enough, because one may need to "import" data formatted with different
national settings from the system's settings.
