@Beta @GwtCompatible(emulated=true) public final class 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.

public static UnsignedInteger asUnsigned(int value)
UnsignedInteger that, when treated as signed, is
equal to value.
public static UnsignedInteger valueOf(long value)
UnsignedInteger that is equal to value,
if possible. The inverse operation of longValue().
public static UnsignedInteger valueOf(BigInteger value)
UnsignedInteger representing the same value as the specified
BigInteger. This is the inverse operation of bigIntegerValue().
IllegalArgumentException - if value is negative or value >= 2^32public static UnsignedInteger valueOf(String string)
UnsignedInteger holding the value of the specified String, parsed
as an unsigned int value.
NumberFormatException - if the string does not contain a parsable unsigned int
value
public static UnsignedInteger valueOf(String string,
int radix)
UnsignedInteger holding the value of the specified String, parsed
as an unsigned int value in the specified radix.
NumberFormatException - if the string does not contain a parsable unsigned int
valuepublic UnsignedInteger add(UnsignedInteger val)
val. If the result would have more than 32 bits,
returns the low 32 bits of the result.
public UnsignedInteger subtract(UnsignedInteger val)
val. If the result would be negative,
returns the low 32 bits of the result.
@GwtIncompatible(value="Does not truncate correctly") public UnsignedInteger multiply(UnsignedInteger val)
val. If the result would have more than 32
bits, returns the low 32 bits of the result.
public UnsignedInteger divide(UnsignedInteger val)
val.
public UnsignedInteger remainder(UnsignedInteger val)
val.
public int intValue()
UnsignedInteger as an int. This is an inverse
operation to asUnsigned(int).
Note that if this UnsignedInteger holds a value >= 2^31, the returned value
will be equal to this - 2^32.
intValue in class Numberpublic long longValue()
UnsignedInteger as a long.
longValue in class Numberpublic float floatValue()
UnsignedInteger as a float, analogous to a widening
primitive conversion from int to float, and correctly rounded.
floatValue in class Numberpublic double doubleValue()
UnsignedInteger as a float, analogous to a widening
primitive conversion from int to double, and correctly rounded.
doubleValue in class Numberpublic BigInteger bigIntegerValue()
UnsignedInteger as a BigInteger.
public int compareTo(UnsignedInteger other)
0 if they are equal, a negative number if this < other,
and a positive number if this > other.
compareTo in interface Comparable<UnsignedInteger>public int hashCode()
hashCode in class Object
public boolean equals(@Nullable
Object obj)
equals in class Objectpublic String toString()
UnsignedInteger value, in base 10.
toString in class Objectpublic String toString(int radix)
UnsignedInteger value, in base radix.
If radix < Character.MIN_RADIX or radix > Character.MAX_RADIX, the radix
10 is used.
