* 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.
