Hi All,

If I use AnsiString::ToDouble(), then this will convert a floating point number
string to a 'float' as per my Regional Settings. For example, if an American
user inputs "5.2" I get 5.2 and if a European user inputs "5,2" I get 5.2. No
problem here.

However, I'm using String("").sprintf("%.03f", MyFloat) to convert back to a
string for output. I get "5.200" independent of Regional Settings. I assume this
is because the sprintf doesn't take these global settings into account. If I use
 StrToFloat, I end up with something like "5.200000384". I am using sprintf so I
can limit the number of significant digits displayed. Is there a way to limit my
sigdigs and utilize the global Regional Settings of Windows?

Many thanks,

Rob
