I am trying to replicate some java code in perl. The operation, I need to perform is to convert Java BigInteger to byte array Java Code: 
public class Main {
    public static void main(String[] args) {
         BigInteger n = new BigInteger("1677259342285725925376");
         System.out.println(Arrays.toString(n.toByteArray()));
    }

}

[download]
Output: [90, -20, -90, 53, 78, -38, 2, -128, 0]

I need to do similar operation in perl, I am completely new in perl. So, no idea. Thanks in advance.
