Rounding error in TRig.ToDPIcom

[jarvisroad]

Hi, I've been using the DPIcom format in a rig descriptor file I created for the AOR AR-DV1 receiver. I found that there is a rounding error when dividing from Hz to MHz on line 321 of RigObj.pas. If I declare F as double (line 316) this rounding problem can be fixed. Would you be able to make this change and include in your next release please?

Hello Steve,

I have already changed the declaration of F to double in RigObj.pas.

Here is the new code:

// Added by RA6UAZ for Icom Marine Radio NMEA Command
procedure TRig.ToDPIcom(Arr: TByteArray; Value: integer);
var
S: AnsiString;
// Changed by Stephan Andratsch (22.07.20209)
// Dataytype change from single to double
// Fix inspired by jarvisroad - Steve Holloway (M7FFT)
F: double;
C: Char;
begin
C := FormatSettings.DecimalSeparator;
FormatSettings.DecimalSeparator := '.';
F := Value / 1000000;
S := StringOfChar('0', Length(Arr)) + FloatToStrF(F,ffFixed,10,6);
Move(S[Length(S)-Length(Arr)+1], Arr[0], Length(Arr));
FormatSettings.DecimalSeparator := C;
end;

Hopefully I will be able to release the new version in a couple of days.

Regards
Stephan Andratsch

Dear Steve & Stephan
It seems than one of you has created a rig descriptor file for the AOR DV-1.
I tried to do this several times without success. Could you please tell me, if this file is public available? It would be a great help for me to see how it's done ( and to use it ).
