> What do people thing about changing num_exact() in time.c to call #rationalize for Floats rather than #to_r?  Or perhaps call #rationalize on the object if it responds to #rationalize so that this won't be exclusive to Floats?

I'm not sure Float#rationalize is good choice.
At least, I don't understand the behavior and
the document don't explain the behavior.
The document describes eps is choosen automatically.
I think it is not enough explanation.
