  * Document-class: Numeric
  *
  * Numeric is the class from which all higher-level numeric classes should inherit.
- * 
+ *
  * Numeric allows instantiation of heap-allocated objects. Other core numeric classes such as
  * Integer are implemented as immediates, which means that each Integer is a single immutable
  * object which is always passed by value.
- * 
+ *
  *   a = 1
  *   puts 1.object_id == a.object_id   #=> true
- * 
+ *
  * There can only ever be one instance of the integer +1+, for example. Ruby ensures this
  * by preventing instantiation and duplication.
- * 
+ *
  *   Integer.new(1)   #=> NoMethodError: undefined method `new' for Integer:Class
  *   1.dup            #=> TypeError: can't dup Fixnum
- * 
+ *
  * For this reason, Numeric should be used when defining other numeric classes.
- * 
+ *
  * Classes which inherit from Numeric must implement +coerce+, which returns a two-member
  * Array containing an object that has been coerced into an instance of the new class
  * and +self+ (see #coerce).
- * 
+ *
  * Inheriting classes should also implement arithmetic operator methods (<code>+</code>,
  * <code>-</code>, <code>*</code> and <code>/</code>) and the <code><=></code> operator (see
  * Comparable). These methods may rely on +coerce+ to ensure interoperability with
  * instances of other numeric classes.
