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.
对Eispack机器epsilon例程的评论
我们分析了用于在Eispack例程套件中为机器epsilon生成值的算法,并表明它在二进制浮点系统上可能会失败。代码中描述此方法工作条件的注释不够严格,因此我们提供了一组替换的假设。最后,我们建议如何修改算法以克服大多数缺点。
