Convert double to byte[] array

Question

How can I convert double to byte array in Java? I looked at many other posts, but couldn\'t figure out the right way.

Input = 65.43 
byte[] size = 6
precisi         


        

Answer 1

public static byte[] encode(double input, int size, int precision) {
    double tempInput = input;

    for (int i = 0; i < precision; i++) tempInput *= 10;

    int output = (int) tempInput;

    String strOut = String.format("%0"+size+"d", output);

    return strOut.getBytes();
}
