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