This question already has an answer here:
How do I change the default precision in Mathematica?
Somehow the setting has been changed to 1 digit, so if I type
which is not very enlightening. Similarly,
Compare Mathematica's documentation for Numerical Precision which says of the above command "In standard output form, Mathematica prints a number like this to six digits." So something isn't right with my setup.
I read the guide to numerical precision but it didn't appear to address this issue.
Note that I do not want to change
PrecisionGoal on a particular function,but just change the default setting. (Of course I'll have to adjust these in some cases, but I just want to have a sensible starting point.)
