請問底下紅字那行的語法有什麼錯?
#define BAUDRATE2 57600 #define BRG_DIV2 4 #define BRGH2 1 #define BAUD_ERROR ((BAUD_ACTUAL > BAUDRATE2) ? BAUD_ACTUAL-BAUDRATE2 : BAUDRATE2-BAUD_ACTUAL) #define BAUD_ERROR_PRECENT ((BAUD_ERROR*100+BAUDRATE2/2)/BAUDRATE2) #if (BAUD_ERROR_PRECENT > 3) #error UART frequency error is worse than 3% #elif (BAUD_ERROR_PRECENT > 2) #warning UART frequency error is worse than 2% #endif 紅色那行的錯誤訊息如以下 error: missing binary operator before token "(" 什麼 binary operator?  為何要 binary operator?
