ABSTRACT
Algorithms are given that compute multiple sums and products and arbitrary roots of floating-point numbers with maximum accuracy, The summation algorithm can be applied to compute scalar products, matrix products, etc. For all these functions, simple error formulas and the smallest floating-point intervals containing the exact result can be obtained.
INDEX TERMS
Accuracy, errors, floating-point computations, multiple-length mantissas, roots of floating-point numbers, rounding.
