Exponential Expressions in Arduino

The pow() function of Arduino can be used for evaluating exponential expressions. Any expression of the form a^b can be expressed as pow(a,b). For example 2³ becomes pow(2,3).

The type for both the base (a) and the exponent (b) is float. This function returns a double.

Example

void setup() {
   // put your setup code here, to run once:
   Serial.begin(9600);
   Serial.println();
   float base = 2;
   float exponent = 3;
   Serial.println(pow(base,exponent));
}

void loop() {
   // put your main code here, to run repeatedly:
}

You are encouraged to try different values of base and exponent and check the working of this function.
