# Generic Arithmetic

Generics became part of the .NET Framework in version 2.0. However, this did not
include the ability to use generic types in arithmetic expressions.
The **Extreme Optimization Numerical Libraries for .NET**
provides a framework for adding generic arithmetic.

The framework consists of two components: a set of interfaces that define arithmetic operations, and a set of attributes that enable the use of specialized implementations that are optimized for specific types.

Built on this foundation is a generic linear algebra library that includes most of the functionality available in the Vector and Matrix Library User's Guide.
