## [edit] 1 Purpose

There have been many ideas for improving the prelude's support for mathematics. Including the addition of algebraic classes. But the discussion is spread over years of list archives and a half dozen websites. And the discussion has never gelled.

This page is intended to collect links to past discussion, and to provide a focal point for advancing the discussion.

## [edit] 2 Todo

- Flesh out list of proposals. First from Libraries_and_tools/Mathematics.
- Add links to discussions in list archive, and elsewhere.

## [edit] 3 Libraries and proposals

### [edit] 3.1 Numeric Prelude

Working set of common type classes and instances.

### [edit] 3.2 Basic Algebra Library (BAL)

- Is not in community report 2006-06.
- 0.04/announce.txt (2006-02)
- www.botik.ru/pub/local/Mechveliani/basAlgPropos/
- Formerly refered to as "basic algebra proposal".

Categorical Approach to representing mathematical structures in Haskell: [1]

### [edit] 3.3 Haskell Prime'

Numeric classes on the Haskell' wiki

### [edit] 3.4 See Also

## [edit] 4 Discussion

*For me that probably starts with the semigroup/group/ring setup, and good*
arbitrary-precision as well as approximate linear algebra support.

*I agree: semigoups like lattices are everywhere. Then there could be a uniform treatment of linear algebra, polynomial equations, operator algebra, etc.*

MAGMA is an example of a language which embraced mathematical structure. MitchellNCharity 23:16, 14 November 2006 (UTC)
