IntToBin(2-16进制转换函数)

(****Value是要转换的十进制数，Count是输出的二进制位数，默认32位****)
function IntToBin(Value: Integer; Count: Integer=32): string;
var
  iTemp: Integer;
begin
  Result := '';
  while Count>0 do
  begin
    iTemp := Value shr (Count-1) and 1;
    case iTemp of
      1: Result := Result+'1';
      0: Result := Result+'0';
    end;
    Dec(Count);
  end;
end;
自己写的，不知有否漏洞，测试了一下
ShowMessage(IntToBin(-1,8));  //输出11111111
ShowMessage(IntToBin(333333)); //输出00000000000001010001011000010101
