This package provides unary type level representations of the
(positive and negative) integers and basic operations (addition,
subtraction, multiplication, division) on these.
Due to the unary implementation the practical size of the
NumTypes is severely limited making them unsuitable for
large-cardinality applications. If you will be working with
integers beyond (-20, 20) this package probably isn't for you.
It is, however, eminently suitable for applications such as
representing physical dimensions (see the Dimensional library).
Requires GHC 6.6.1 or later.
Changes
1.1 (2014-02)
GHC 7.8.1 compatibility fix.
Added a Sub c b a constraint to Sum a b c. This
prevents a liberal coverage condition failure on GHC 7.8.1 RC1.
I don’t expect this to break any existing code but am updating
the major version number just in case.
