according to Arduino website 2 integers can be divided.

So I tried

int a =33;
int b =55;


void setup() {

Serial.begin(115200); // main mac port to teensy
}

void loop() {
double c= a/b;

Serial.println (c);
delay (1000);

}

I get 0.00

What am I missing, must be super elementary , sorry....

Thanks
