  - byteValue
```
public byte byteValue()
```
    Returns this object's value as a byte. Might involve rounding and/or truncating the value, so it fits into a byte.
    
    Returns:
    
    the primitive byte value of this object.
  - doubleValue
```
public abstract double doubleValue()
```
    Returns this object's value as a double. Might involve rounding.
    
    Returns:
    
    the primitive double value of this object.
  - floatValue
```
public abstract float floatValue()
```
    Returns this object's value as a float. Might involve rounding.
    
    Returns:
    
    the primitive float value of this object.
  - intValue
```
public abstract int intValue()
```
    Returns this object's value as an int. Might involve rounding and/or truncating the value, so it fits into an int.
    
    Returns:
    
    the primitive int value of this object.
  - longValue
```
public abstract long longValue()
```
    Returns this object's value as a long. Might involve rounding and/or truncating the value, so it fits into a long.
    
    Returns:
    
    the primitive long value of this object.
  - shortValue
```
public short shortValue()
```
    Returns this object's value as a short. Might involve rounding and/or truncating the value, so it fits into a short.
    
    Returns:
    
    the primitive short value of this object.
