On the maximum relative error when computing integer powers by iterated multiplications in floating-point arithmetic
Résumé
We improve the usual relative error bound for the computation of x^n through iterated multiplications by x in binary floating-point arithmetic. The obtained error bound is only slightly better than the usual one, but it is simpler. We also discuss the more general problem of computing the product of n terms.
