- Constructor Detail
  - NumberT
```
public NumberT(NumberT.Kind kind)
```
    Create a new number type. The specified kind must be a valid integer or float kind.
    
    Parameters:
    kind - The kind.
  - NumberT
```
public NumberT(Type template,
       NumberT.Kind kind)
```
    Create a new number type. The specified kind must be a valid integer or float kind.
    
    Parameters:
    template - The type whose annotations to copy.
    kind - The kind.
- Method Detail
  - isNumber
```
public boolean isNumber()
```
    Description copied from class: Type
    
    Determine whether this type is a number.
    
    Overrides:
    
    isNumber in class Type
    
    Returns:
    true if this type is a number.
  - toNumber
```
public NumberT toNumber()
```
    Description copied from class: Type
    
    Get this type as a number.
    
    Overrides:
    
    toNumber in class Type
    
    Returns:
    This type as a number.
  - hasKind
```
public boolean hasKind(NumberT.Kind kind)
```
    Determine whether this number has the specified kind. Note that this method uses equal(Kind,Kind) to perform the kind comparison.
    
    Parameters:
    kind - The kind.
    
    Returns:
    true if this number has the specified kind.
  - getKind
```
public NumberT.Kind getKind()
```
    Get the kind.
    
    Returns:
    The kind.
  - isSigned
```
public boolean isSigned()
```
    Determine whether this number is signed.
    
    Returns:
    true if this number is signed.
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class java.lang.Object
  - equals
```
public boolean equals(java.lang.Object o)
```
    Determine whether this type equals the specified object. This number equals the specified object if the specified object also is a number and the two numbers' kinds are either the same or a combination of the int and signed int kinds.
    
    Overrides:
    
    equals in class java.lang.Object
    
    Parameters:
    o - The object.
    
    Returns:
    true if this type equals the object.
  - write
```
public void write(java.lang.Appendable out)
           throws java.io.IOException
```
    Description copied from class: Node
    
    Write a human readable representation to the specified appendable. If this node supports generic traversal, the default implementation writes this node in algebraic term-format; otherwise, it writes the string returned by Object.toString().
    
    Overrides:
    
    write in class Node
    
    Parameters:
    out - The appendable.
    
    Throws:
    
    java.io.IOException - Signals an I/O error.
  - toString
```
public java.lang.String toString()
```
    Description copied from class: Node
    
    Return a human readable representation of this node. The default implementation creates a new string builder, writes this node to the builder, and then returns the corresponding string. Subclasses should typically override Node.write(Appendable).
    
    Overrides:
    
    toString in class Node
    
    Returns:
    A human readable representation.
  - equal
```
public static boolean equal(NumberT.Kind k1,
            NumberT.Kind k2)
```
    Determine whether the specified kinds equal each other. This method treats implicit, int, and signed int types as equal.
    
    Parameters:
    k1 - The first kind.
    k2 - The second kind.
    
    Returns:
    true if the kinds are equal.
  - equalIgnoringSign
```
public static boolean equalIgnoringSign(NumberT.Kind k1,
                        NumberT.Kind k2)
```
    Determine whether the specified kinds equal each other, modulo their signs. This method treats implicit, int, and signed int types as equal.
    
    Parameters:
    k1 - The first kind.
    k2 - The second kind.
    
    Returns:
    true if the kinds are equal modulo their signs.
