No, it is an integer number.
Correlations happen among various different things. A non-zero correlation means that the things interact or depend on each other. A zero correlation means they don't.
Examples: There is a positive correlation between how much you eat and how much you weigh. There is a zero correlation between the color of your car and its gas mileage. There is a positive correlation between how far the volume control is turned up and the sound pressure level that you hear. There is a negative correlation between the air temperature and the sales of sweaters.
