bitClear()
설명
숫자 변수의 한 비트를 지웁니다(그 자리에 0을 씀).
문법
bitClear(x, n)
매개변수
- x: 비트를 지울 숫자 변수
- n: 지울 비트의 위치, LSB(맨 오른쪽 비트)가 0, 왼쪽으로 갈수록 1씩 증가
반환값
- 없음
예제 코드
Demonstrates the use of bitClear() by printing the value of a variable to the Serial Monitor before and after the use of bitClear().
void setup() {
Serial.begin(9600);
byte x = 0b10000100; // the 0b prefix indicates a binary constant
Serial.print("BEFORE: ");
Serial.println(x, BIN); // 10000100
bitClear(x, 2); // clear the third bit
Serial.print("AFTER: ");
Serial.println(x, BIN); // 10000000
}
void loop() {}
The result in Serial Monitor:
8
Serial.println("Hello World!");
