@GwtCompatible(serializable=true)
public final class UnsignedLong
extends Number
implements Comparable<UnsignedLong>, Serializable
```
A wrapper class for unsigned long values, supporting arithmetic operations.
In some cases, when speed is more important than code readability, it may be faster simply to treat primitive long values as unsigned, using the methods from UnsignedLongs.
See the Guava User Guide article on unsigned primitive utilities.

  - fromLongBits
```
public static UnsignedLong fromLongBits(long bits)
```
    Returns an UnsignedLong corresponding to a given bit representation. The argument is interpreted as an unsigned 64-bit value. Specifically, the sign bit of bits is interpreted as a normal bit, and all other bits are treated as usual.
    If the argument is nonnegative, the returned result will be equal to bits, otherwise, the result will be equal to 2^64 + bits.
    To represent decimal constants less than 2^63, consider valueOf(long) instead.

```
@CanIgnoreReturnValue
public static UnsignedLong valueOf(long value)
```
    Returns an UnsignedLong representing the same value as the specified long.
    
    Throws:
    
    IllegalArgumentException - if value is negative

```
@CanIgnoreReturnValue
public static UnsignedLong valueOf(BigInteger value)
```
    Returns a UnsignedLong representing the same value as the specified BigInteger. This is the inverse operation of bigIntegerValue().
    
    Throws:
    
    IllegalArgumentException - if value is negative or value >= 2^64
