ArduinobitClear()
Clears (writes a 0 to) a bit of a numeric variable.
Syntax
bitClear(x, n)
Parameters
x: the numeric variable whose bit to clear.
n: which bit to clear, starting at 0 for the least-significant (rightmost) bit.
Returns
x: the value of the numeric variable after the bit at position n is cleared.
Example Code
Prints the output of bitClear(x,n) on two given integers. The binary representation of 6 is 0110, so when n=1, the second bit from the right is set to 0. After this we are left with 0100 in binary, so 4 is returned.
void setup() {
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}
int x = 6;
int n = 1;
Serial.print(bitClear(x, n)); // print the output of bitClear(x,n)
}
void loop() {
}
