## 1 Abstract

Any applicative functor can be given numeric instances in a boilerplate way.
The **applicative-numbers** package provides an include file that makes it a snap to define these instances.

Besides this wiki page, here are more ways to find out about applicative-numbers:

- Visit the Hackage page for library documentation and to download & install.
- Or install with
`cabal install applicative-numbers`. - Get the code repository:
`darcs get http://code.haskell.org/~conal/code/applicative-numbers`.
