Description
Met à 0 un bit d'une variable numérique.
Syntaxe
bitClear(x, n)
Paramètres
- x: la variable numérique dans laquelle il faut mettre un bit à 0
- n: le rang du bit qui doit être mis à 0 , en démarrant à 0 pour le bit de poids faible (le plus à droite)
Valeurs Renvoyées
- Aucune
Exemple
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:
COM6
BEFORE: 10000100
AFTER: 10000000
