Comment (by SimonKing):
I tried the example with sage-6.5.beta4, and it works fine:
{{{
sage: GaussianIntegers = NumberField(x^2+1, 'I').ring_of_integers()
sage: A = GaussianIntegers([2,1])
sage: A.n??
Type: builtin_function_or_method
String form: <built-in method numerical_approx of
sage.rings.number_field.number_field_element_quadratic.OrderElement_quadratic
object at 0x7f2c4fbb6650>
Definition: A.n(self, prec=None, digits=None, algorithm=None)
Source:
def numerical_approx(self, prec=None, digits=None, algorithm=None):
"""
Return a numerical approximation of x with at least prec bits of
precision.
EXAMPLES::
sage: (2/3).n()
0.666666666666667
sage: pi.n(digits=10)
3.141592654
sage: pi.n(prec=20) # 20 bits
3.1416
TESTS:
Check that :trac:`14778` is fixed::
sage: (0).n(algorithm='foo')
0.000000000000000
"""
import sage.misc.functional
return sage.misc.functional.numerical_approx(self, prec=prec,
digits=digits,
algorithm=algorithm)
Init docstring: x.__init__(...) initializes x; see help(type(x)) for
signature
}}}
So, we should have a look at changes in sageinspect that have occurred
since 6.5.beta4.
