The papers in this special issue focus on computer arithmetic which is used in many
applications, usually totally silently (one should keep in mind that even when running
programs that are not at all numeric, memory addresses are computed, which involves
additions, multiplications, and sometimes divisions). However, in some areas, it plays a
central role.

Advances in technology continue to make it feasible to implement ever more complex
algorithms directly in hardware. Almost invariably, arithmetic calculations are at the core of
most algorithms to be implemented. They play an especially crucial role in applications
where speed is essential, for example, in digital signal processing, in cryptography, and in
telecommunications. This requirement for higher speed must be realized in concert with
satisfying user demands for higher precision. Papers in this Special Issue cover various …
