The best way is probably to use mpmath.mpmath_to_sage(). Just note
that you have to provide the desired precision as well as the number
to convert.

Perhaps this is the kind of thing you want?
sage: var('x')
sage: f = -x^4 + 9*x^3 - 23*x^2 + 31*x - 15
sage: f.find_maximum_on_interval(0,6)
(69.216599407272753, 4.6263272799362944)
If you do
sage: f.find_maximum_on_interval?
you can get the documentation for that. For symbolic answers you

Thanks -- Yann's link explained everything. Since it happened to be
the first thing I tried in sage, I ascribed my surprise to it, but it
turned out I hadn't understood "fromfunction" properly.
Sorry about that!

Dear Fredrik,
It seems that it is possible to convert from mpf to Sage reals
seemlessly:
sage: import sage.libs.mpmath.all as mpmath
sage: r = mpmath.mpf('1.00193')
sage: r
You can find the answer here (look for fromfunction):

The answer is in the code of sage.server.notebook.css : just need to
write a css sheet named notebook.css in the DOT_SAGE path
The remaining (minor) problem is that this configuration applies for
all the worksheets ! It could be nice to have an option in each
worksheet...

Hello,
I would like to consider some HTML styles in a worksheet (principally
controlling margins and fonts). For example, I would be able do define
a style for definitions, another one for theorems and so on. My actual
