The Currency type is a fixed-point data type suitable for monetary
calculations.
It is stored as a scaled 64-bit integer with the four
least-significant digits implicitly representing four decimal places.

A currency is a Int64, which is the currency amount multiplied by 1.
Well, apparently Delphi 6 RTTI thinks that it is a float. Check this code:
A currency

Interresting enough, the exact same value is returned. From my
research on
Hello,
I managed to read the extended by putting it in a program like this:
procedure TForm1.Button1Click(Sender: TObject);
var
Hex: array[0..9] of Byte;
Num: Extended;
begin
Hex[0] := $00;
Hex[1] := $00;
Hex[2] := $00;
Hex[3] := $00;
Hex[4] := $00;
Hex[5] := $00;
Hex[6] := $00;

For single and double there is a nice converter which shows the binary layout:

Unfortunately there seams to be much less resources about extended...

Hello,
I am interfacing with a server written in Delphi via network and it

The server is undocumented and does some strange transformations of
the data using RTTI to pass properties.
