Just do:

> sage: s.global_height?
> }}}
> You should now see documentation on how to use the global height. The
examples like:
> {{{
> sage: R.<x> = QQ[]
> sage: K.<a> = NumberField(x^4+3*x^2-17)
> sage: b = a/2
> sage: b.global_height()
> 2.869222240687...
> sage: b.global_height(prec=200)
> 2.8692222406879748488543678846959454765968722137813736080066
> }}}
> given there are called doctests since they are used for automated
testing of the sage library (see
http://www.sagemath.org/doc/developer/doctesting.html). All those examples
are tested and should produce the shown output before a patch is accepted.
In this case it means that the doctests have to change since the answers
show are not correct. What john asked is if you could also add your
example wich you posted in the description as a test (ofcourse with the
new and imporved answers.
Ok, thanks for the explanation. Unfortunately, I can't put in those
examples yet, because my sage library won't build. So even though I've
made the changes in the code, I can't get sage to recognize them. I have
this problem on my personal computer, and also on the ones in my
department.. do you think this problem with Lion and Xcode will be fixed
any time soon?
