Function
sqrt(x);
Parameter
x: could be any data type
Example
Next it is showed a simple example of how to print a square root of an analog value every second.
long number = 0;
void setup() {
Serial.begin(9600L);
}
void loop() {
number = sqrt(analogRead(I0_7));
Serial.println(number);
delay(1000);
}
