Delphi 2005 Floating Point operations on Vista-64 1

[Andy650]

I have a Delphi 9.0 (2005) application that calls the following simple code (sanitized for ease of explanation)...

procedure MyProc;
var
  myNumber: Extended; // tried Real here also
  myString: String;
begin
  myString := '9.04';
  myNumber := strToFloat(myString);
  showMessage(floatToStr(myNumber));
end;

Running on XP SP3 all is well as you would expect but on a client's Vista-64 machine, it is raising an exception: '9.04' is not a valid floating point value

Are there known compatability issues with this function (and any others whilst we're at it) and any documented alternatives for this Delphi version?

Many thanks.

I suspect that the regional settings different on the vista machine (having ',' as decimalseparator).

the fix should be easy:

set decimalseparator value to '.' at application initialization.

[Slaps forehead]. As soon as I heard Vista-64 I started to overthink it with paranoia about flop issues. I'll try it on the client site next week but you gotta be right!

Like the old saying goes. If you hear hoofbeats - think horses not zebras.

Cheers fella!
