Associations are a way of associating dictionaries of
|
|
operations with given types at runtime. Associations are global to a
|
|
.NET application domain. Once specified an association may not be deleted
|
|
or modified.
|
|
|
|
In this release the system of associations is simply
|
|
limited to a registry of types that support dictionaries (i.e. interface objects)
|
|
of numeric operations. The following types are pre-registered with associated numeric
|
|
operations: float, int32, int64, bigint, float32, Complex, bignum. Other types must be
|
|
registered explicitly by user code.
