Tuesday August 21, 2007 Unsigned long in Java
I needed to get the unsigned value of the bytes in a long. Took some digging, but this finally worked for me:
long longValue;
...// set longValue to something
BigInteger bi = new BigInteger(
Long.toHexString(longValue),16
);
You can then use the methods on BigInteger to get your value. I needed the raw unsigned bytes, so I called bi.toByteArray().
