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
