In my code, I have float Hz = 0.00; I want to display values to my user in RPM as

Serial.print("Speed = ");
Serial.println(" RPM);

The only hangup is that this displays as Speed = XX.00 RPM is there an easy way to get the Arduino to only print out Speed = XX RPM?

From the documentation:

Serial.print(round(Hz*60), 0);
