  - fromIEEE754BIDEncoding
```
public static Decimal128 fromIEEE754BIDEncoding(long high,
                                                long low)
```
    Create an instance with the given high and low order bits representing this Decimal128 as an IEEE 754-2008 128-bit decimal floating point using the BID encoding scheme.
    
    Parameters:

    low - the low-order 64 bits
    
    Returns:
    
    the Decimal128 value representing the given high and low order bits
  - getHigh
```
public long getHigh()
```
    Gets the high-order 64 bits of the IEEE 754-2008 128-bit decimal floating point encoding for this Decimal128, using the BID encoding scheme.
    
    Returns:
    
    the high-order 64 bits of this Decimal128
  - getLow
```
public long getLow()
```
    Gets the low-order 64 bits of the IEEE 754-2008 128-bit decimal floating point encoding for this Decimal128, using the BID encoding scheme.
    
    Returns:
    
    the low-order 64 bits of this Decimal128
  - bigDecimalValue
```
public BigDecimal bigDecimalValue()
```
    Gets a BigDecimal that is equivalent to this Decimal128.
    
    Returns:
    
    a BigDecimal that is equivalent to this Decimal128
    
    Throws:
    
    ArithmeticException - if the Decimal128 value is NaN, Infinity, -Infinity, or -0, none of which can be represented as a BigDecimal
  - isNegative
```
public boolean isNegative()
```
    Returns true if this Decimal128 is negative.
    
    Returns:
    
    true if this Decimal128 is negative
  - isInfinite
```
public boolean isInfinite()
```
    Returns true if this Decimal128 is infinite.
    
    Returns:
    
    true if this Decimal128 is infinite
  - isFinite
```
public boolean isFinite()
```
    Returns true if this Decimal128 is finite.
    
    Returns:
    
    true if this Decimal128 is finite
  - isNaN
```
public boolean isNaN()
```
    Returns true if this Decimal128 is Not-A-Number (NaN).
    
    Returns:
    
    true if this Decimal128 is Not-A-Number
  - equals
```
public boolean equals(Object o)
```
    Returns true if the encoded representation of this instance is the same as the encoded representation of o.
    One consequence is that, whereas Double.NaN != Double.NaN, new Decimal128("NaN").equals(new Decimal128("NaN") returns true.
    
    Another consequence is that, as with BigDecimal, new Decimal128("1.0").equals(new Decimal128("1.00") returns false, because the precision is not the same and therefore the representation is not the same.
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    o - the object to compare for equality
    
    Returns:
    
    true if the instances are equal
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - toString
```
public String toString()
```
    Returns the String representation of the Decimal128 value.
    
    Overrides:
    
    toString in class Object
    
    Returns:
    
    the String representation
