New description:
The simple fraction
{{{
i/2* x^2/a
}}}
is typeset as
{{{
1/2* i x^2/ (2*a).
}}}
This is clearly wrong. There is an extra factor of 2 in the denominator.
The internal representation is however correct.
Reproduce with
{{{
var('a x')
ratio = i/2* x^2/a
print ratio # correct
latex(ratio) # wrong
}}}
See my public worksheet http://demo.sagenb.org/home/pub/69/ (sage version
4.6)
Apply trac_10679-quadratic_number_field_numerator.patch,
trac_10679-py_numer.patch.

Comment:
Attached patches fix this issue.
* attachment:trac_10679-quadratic_number_field_numerator.patch defines a
`numerator()` method for quadratic number field elements
* attachment:trac_10679-py_numer.patch changes the `py_numer()` function
so that it will still work when it encounters another element class that
defines `denominator()` but not `numerator()`
