خوب چه مشکلی پیش میاد دوست عزیز ؟
توضیح بدید لطفا

این قسمت floatToStr ایراد میگیره


ok:=false;
if pos('.',FloatToStr(i)) <> 0 then
jj := copy( FloatToStr(i),1,pos('.',FloatToStr(i))-1)
else jj := FloatToStr(i);
j := StrToInt64Def(jj,0);
result:=seragham(j div 1000000000000);
if ok then result:=result+I_tr+v;
result:=result+seragham((j mod 1000000000000)div 1000000000);
if ok then result:=result+I_mr+v;
result:=result+seragham((j mod 1000000000)div 1000000);
if ok then result:=result+I_ml+v;
result:=result+seragham((j mod 1000000)div 1000);
if ok then result:=result+I_hz+v;
result:=result+seragham(j mod 1000);
if not ok then result:=copy(result,1,length(result)-3);

if pos('.',FloatToStr(i)) <> 0 then begin
Result := Result + ' ããíÒ ';
jj := copy( FloatToStr(i),pos('.',FloatToStr(i))+1,100);
j := StrToInt64Def(jj,0);

result:=result + seragham(j div 1000000000000);
if ok then result:=result+I_tr+v;
result:=result+seragham((j mod 1000000000000)div 1000000000);
if ok then result:=result+I_mr+v;
result:=result+seragham((j mod 1000000000)div 1000000);
if ok then result:=result+I_ml+v;
result:=result+seragham((j mod 1000000)div 1000);
if ok then result:=result+I_hz+v;
result:=result+seragham(j mod 1000);
if not ok then result:=copy(result,1,length(result);-3);

Result := Result + FloatPoint[length(JJ)];


end;


if i=0 then result:='Ziro';
end;
end.

...

if not ok then

      result := copy(result, 1, length(result) - 3);



    result := result + FloatPoint[length(JJ)];



  end;



  if i = 0 then

    result := 'Ziro';

end;

کجاست یاری دهنده ای که مرا یاری کند؟:افسرده:
