>Hei,Oleg, I am afraid that you are barking under the wrong tree. The problem of calculation precision depends mostly on the problem singularity AND computational formula's representation. There exists a whole discipline of computational error spreading in the parsing tree, f.e. W.Miller. SIAM J on Computing June 1976, Graph transformations for roundoff analysis. Just adding n numbers makes your result faulty by SQR(n) last exact units ... With best regards Leo
