Do you agree that the original proposed use (helping newbs ignore floating
point realities) is misguided and error-prone?

Just curious, for your needs, do you want both absolute and relative 
checks combined into the same function?

The unittest module already has assertAlmostEqual().  Does that
method meet your needs or does it need to be improved in some way?
