Try this:

function ConvertToPriceAndDescr(str: string; var price: integer; var descr: string) : boolean;
begin
  result:=false;
  Trim(str);
  i1:=Pos(' ',str);
  descr:=Copy(str,i1,maxInt);
  Trim(descr);
  Delete(str,i1,maxInt);
  i1:=1;
  while (i1<=length(str)) and (not (str[i1] in ['0'..'9'])) do
    inc(i1);
  Delete(str,1,i1-1);
  i1:=Pos('.',str);
  try
    price:=StrToInt(Copy(str,1,i1-1))*100 + StrToInt(Copy(str,i1+1,maxInt));
  except exit end;
  result:=true;
end;

In your example the result would be: "price=10000" and "descr='Range Hood'". To get the cents, devide price with 100.

Regards, Madshi.
