API for generic.arithmetic - clojure-contrib v1.2 (beta 1)

by Konrad Hinsen
Usage: 
(ns your-namespace
  (:require clojure.contrib.generic.arithmetic))

Overview


Generic arithmetic interface
This library defines generic versions of + - * / as multimethods
that can be defined for any type. The minimal required 
implementations for a type are binary + and * plus unary - and /.
Everything else is derived from these automatically. Explicit
binary definitions for - and / can be provided for
efficiency reasons.






Public Variables and Functions



  

  

  
*

  multimethod

  
Usage: (* x)
       (* x y)
       (* x y & more)


  
Return the product of all arguments. The minimal implementation for type
::my-type is the binary form with dispatch value [::my-type ::my-type].

  
  
  Source


  

  

  
+

  multimethod

  
Usage: (+ x)
       (+ x y)
       (+ x y & more)


  
Return the sum of all arguments. The minimal implementation for type
::my-type is the binary form with dispatch value [::my-type ::my-type].

  
  
  Source


  

  

  
-

  multimethod

  
Usage: (- x)
       (- x y)
       (- x y & more)


  
Return the difference of the first argument and the sum of all other
arguments. The minimal implementation for type ::my-type is the binary
form with dispatch value [::my-type ::my-type].

  
  
  Source


  

  

  
/

  multimethod

  
Usage: (/ x)
       (/ x y)
       (/ x y & more)


  
Return the quotient of the first argument and the product of all other
arguments. The minimal implementation for type ::my-type is the binary
form with dispatch value [::my-type ::my-type].

  
  
  Source


  

  

  
defmethod*

  macro

  
Usage: (defmethod* ns name & args)


  
Define a method implementation for the multimethod name in namespace ns.
Required for implementing the division function from another namespace.

  
  
  Source


  

  

  
qsym

  macro

  
Usage: (qsym ns sym)


  
Create the qualified symbol corresponding to sym in namespace ns.
Required to access the division function from another namespace,
e.g. as (qsym clojure.contrib.generic.arithmetic /).
