Except that they're only a beginner once.  Tell them how to change it,
point out the numerous web pages that explain floating-point etc.   Once
they're past that stage, the defaults may be annoying.

And what about printing of bfloats?  Bfloats are now printed with the
specified precision.  When I use bfloats, I want to see all the extra
digits.   Otherwise, double floats probably would have sufficed.

I guess the smiley was not enough?  I would think that if you can't
understand some points about floating-point, and can't understand
scientific notation (as someone else mentioned), then I would think most
of the symbolic stuff would be incomprehensible.  (That's a generic
"you", not, you, Jay, in particular.)

But since I've been out of school for a long time, perhaps I am no
longer in touch with what students are capable of these days.
