All arithmetic operations can be decomposed into an infinitely accurate calculation and a subsequent rounding quantization. The kind of rounding in use determines the properties of the whole arithmetic system. The article discusses tools for the analysis of the effects of rounding errors during arithmetic calculations. The engineering approach is introduced and the applicability of interval arithmetic is also examined for low-precision systems.
