UnsignedInteger (Guava: Google Core Libraries for Java 23.4-jre API)

java.lang.Object
- java.lang.Number

All Implemented Interfaces:

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

- Method Detail
  - fromIntBits
```
public static UnsignedInteger fromIntBits(int bits)
```
    Returns an UnsignedInteger corresponding to a given bit representation. The argument is interpreted as an unsigned 32-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 2^32 + bits.
    To represent unsigned decimal constants, consider valueOf(long) instead.

  - valueOf
```
public static UnsignedInteger valueOf(long value)
```
    Returns an UnsignedInteger that is equal to value, if possible. The inverse operation of longValue().
  - valueOf
```
public static UnsignedInteger valueOf(BigInteger value)
```
    Returns a UnsignedInteger representing the same value as the specified BigInteger. This is the inverse operation of bigIntegerValue().
    
    Throws:
    
    IllegalArgumentException - if value is negative or value >= 2^32
  - valueOf
```
public static UnsignedInteger valueOf(String string)
```
    Returns an UnsignedInteger holding the value of the specified String, parsed as an unsigned int value.
    
    Throws:
    
    NumberFormatException - if the string does not contain a parsable unsigned int value
  - valueOf
```
public static UnsignedInteger valueOf(String string,
                                      int radix)
```
    Returns an UnsignedInteger holding the value of the specified String, parsed as an unsigned int value in the specified radix.
    
    Throws:
    
    NumberFormatException - if the string does not contain a parsable unsigned int value
  - plus
```
public UnsignedInteger plus(UnsignedInteger val)
```
    Returns the result of adding this and val. If the result would have more than 32 bits, returns the low 32 bits of the result.
    
    Since:
    
    14.0
  - minus
```
public UnsignedInteger minus(UnsignedInteger val)
```
    Returns the result of subtracting this and val. If the result would be negative, returns the low 32 bits of the result.
    
    Since:
    
    14.0
  - times
```
@GwtIncompatible
public UnsignedInteger times(UnsignedInteger val)
```
    Returns the result of multiplying this and val. If the result would have more than 32 bits, returns the low 32 bits of the result.
    
    Since:
    
    14.0

  - intValue
```
public int intValue()
```
    Returns the value of this UnsignedInteger as an int. This is an inverse operation to fromIntBits(int).
    Note that if this UnsignedInteger holds a value >= 2^31, the returned value will be equal to this - 2^32.

```
public String toString()
```
    Returns a string representation of the UnsignedInteger value, in base 10.
