set ipython's default scientific notation threshold

Question

How can I modify the point at which python decides to print in scientific notation?

E.g. I\'d like everything > 1e4 or < 1e-4 to be p

Answer 1

In IPython you can use

%precision %.4g

this will print floating point values who's absolute value is < 1e-4 or >= 1e4 in scientific notation.

You can find more information about the %precision command in the IPython API Docs. For string formatting options have a look at the Python Docs
