libghc-semirings-dev binary package in Ubuntu Lunar amd64
Haskellers are usually familiar with monoids and semigroups. A monoid has an
appending operation `<>` (or `mappend`), and an identity element, `mempty`.
A semigroup has an appending `<>` operation, but does not require a `mempty`
element.
.
A Semiring has two appending operations, `plus` and `times`, and two
respective identity elements, `zero` and `one`.
.
More formally, a Semiring R is a set equipped with two binary relations `+`
and `*`, such that:
.
(R,+) is a commutative monoid with identity element 0,
.
(R,*) is a monoid with identity element 1,
.
(*) left and right distributes over addition, and
.
multiplication by '0' annihilates R.
.
This package provides a library for the Haskell programming language.
