      public abstract class Number
      extends Object
      implements Serializable
The abstract class `Number` is the superclass of platform classes representing numeric values that are convertible to the primitive types `byte`, `double`, `float`, `int`, `long`, and `short`. The specific semantics of the conversion from the numeric value of a particular `Number` implementation to a given primitive type is defined by the `Number` implementation in question. For platform classes, the conversion is often analogous to a narrowing primitive conversion or a widening primitive conversion as defining in The Java™ Language Specification for converting between primitive types. Therefore, conversions may lose information about the overall magnitude of a numeric value, may lose precision, and may even return a result of a different sign than the input. See the documentation of a given `Number` implementation for conversion details. Since: 1.0 See Also: Serialized Form See The Java™ Language Specification : 5.1.2 Widening Primitive Conversions, 5.1.3 Narrowing Primitive Conversions

### constructor:Number() [NONE]
- #### Number
      public Number()

### method:intValue() [NONE]
- #### intValue
      public abstract int intValue()
Returns the value of the specified number as an `int`, which may involve rounding or truncation. Returns: the numeric value represented by this object after conversion to type `int`.

### method:longValue() [NONE]
- #### longValue
      public abstract long longValue()
Returns the value of the specified number as a `long`, which may involve rounding or truncation. Returns: the numeric value represented by this object after conversion to type `long`.

### method:floatValue() [NONE]
- #### floatValue
      public abstract float floatValue()
Returns the value of the specified number as a `float`, which may involve rounding. Returns: the numeric value represented by this object after conversion to type `float`.

### method:doubleValue() [NONE]
- #### doubleValue
      public abstract double doubleValue()
Returns the value of the specified number as a `double`, which may involve rounding. Returns: the numeric value represented by this object after conversion to type `double`.

### method:byteValue() [NONE]
- #### byteValue
      public byte byteValue()
Returns the value of the specified number as a `byte`, which may involve rounding or truncation. This implementation returns the result of `intValue()` cast to a `byte`. Returns: the numeric value represented by this object after conversion to type `byte`. Since: 1.1

### method:shortValue() [NONE]
- #### shortValue
      public short shortValue()
Returns the value of the specified number as a `short`, which may involve rounding or truncation. This implementation returns the result of `intValue()` cast to a `short`. Returns: the numeric value represented by this object after conversion to type `short`. Since: 1.1
