You're right, it would have been more accurate for me to say a *few*
hundredths of a degree.  But that still justifies more than one decimal
place of precision.  A few hundredths of a degree change of descent angle
moves the VSI needle almost as much as a one-degree heading change moves the
HI (and courses are routinely specified with single-degree precision).
