Title: A description and comparison of subroutines for computing Euclidean inner products on the IBM 360
Author: Malcolm, Michael A.
Date: October 1970
Abstract: Several existing subroutines and an Algol W procedure for computing inner products on the IBM 360, using more precision than long, are described and evaluated. Error bounds (when they exist) and execution timing tests are included.
