public final class BigIntegerValue
extends IntegerValue
```
An integer value: note this is a subtype of decimal in XML Schema, not a primitive type. The abstract class IntegerValue is used to represent any xs:integer value; this implementation is used for values that do not fit comfortably in a Java long; including the built-in subtype xs:unsignedLong

                       AtomicType typeLabel)
```
    Construct an xs:integer value from a Java BigInteger, supplying a type label. It is the caller's responsibility to ensure that the supplied value conforms with the rules for the specified type.
    
    Parameters:
    
    value - the value of the integer
    
    typeLabel - the type, which must represent a type derived from xs:integer
  - BigIntegerValue
```
public BigIntegerValue(long value)
```
    Construct an xs:integer value from a Java long. Note: normally, if the value fits in a long, then an Int64Value should be used. This constructor is largely for internal use, when operations are required that require two integers to use the same implementation class to be used.
    
    Parameters:
    
    value - the supplied Java long
