Computer arithmetic

From Wikipedia, the free encyclopedia

Computer arithmetic is the scientific field that deals with representation of numbers on computers and corresponding implementations of the arithmetic operations.[1]

It includes:

In the cases where the size of the representation of a number is fixed (fixed-point, floating-point and interval arithmetic), the main concern is the control the computational error, as far as possible; see, for example IEEE 754.

In the other cases, where an exact result should be provided, the main concern is the practical efficiency, which is optimized by combining improvements of computational complexity with hardware specificities.

ARITH Symposium on Computer Arithmetic is an international symposium devoted to computer arithmetic.
