Hi everybody!
I'd like to know if there is a way of say Sage to return a result in
scientific notation by default, as well as controlling the number of
significant digits.
There is a very big patch on trac [1] that improves the options for
printing real numbers quite a bit (on a per-field basis, you can specify
rounding of the last few digits, whether to show zeroes at the end of
the number, and scientific notation settings). The patch also adds a
lot of doctests to the RealField code.
And the patch is up for review :).
The patch doesn't make it possible to control the number of significant
digits, but it does provide a nice framework for adding that option too.
Thanks,
Jason
