Abstract
We analyze the algorithm used to generate the value for the machine epsilon in the Eispack suite of routines and show that it can fail on a binary floating-point system. The comments in the code describing the conditions under which this method will work are not restrictive enough and we provide a replacement set of assumptions. We conclude by suggesting how the algorithm may be modified to overcome most of the shortcomings.
