Thanks, I have changed the commit message.
comment:8 Changed 5 years ago by
- Status changed from needs_review to positive_review
Everything still works.
comment:9 Changed 5 years ago by
- Status changed from positive_review to needs_work
- Work issues set to docstring
The indentation of the documentation should be
""" Documentation here """
without the extra indent.
comment:10 Changed 5 years ago by
- Status changed from needs_work to needs_review
I have fixed the indentation in the documentation.
comment:11 Changed 5 years ago by
- Status changed from needs_review to needs_work
The indentation is still wrong. It should be:
def global_height(self, prec=None): r""" Returns the absolute logarithmic height of this rational integer. INPUT: - ``prec`` (int) -- desired floating point precision (default: default RealField precision). OUTPUT: (real) The absolute logarithmic height of this rational integer. ALGORITHM: The height of the integer `n` is `\log |n|`. EXAMPLES:: sage: ZZ(5).global_height() 1.60943791243410 sage: ZZ(-5).global_height(prec=100) 1.6094379124341003746007593332 # This is log(5): sage: exp(_) 5.0000000000000000000000000000 """

Thanks for your patience. I've uploaded a new version with the indentation as you specified.

I get the following error with the patch...
sage -t --long integer.pyx ********************************************************************** File "integer.pyx", line 4150, in sage.rings.integer.Integer.global_height Failed example: ZZ(-5).global_height(prec=100) Expected: 1.6094379124341003746007593332 # This is log(5): Got: 1.6094379124341003746007593332 ********************************************************************** 1 item had failures: 1 of 4 in sage.rings.integer.Integer.global_height [916 tests, 1 failure, 5.69 s] ---------------------------------------------------------------------- sage -t --long integer.pyx # 1 doctest failed ---------------------------------------------------------------------- Total time for all tests: 6.0 seconds cpu time: 4.5 seconds cumulative wall time: 5.7 seconds
It's the only error I get, but I don't see why it appears. Since the two values it prints (expected and got) are the same.

Perhaps the comment on the next line threw it off. I've removed it and put a better example. Should work now.
comment:15 Changed 5 years ago by
- Status changed from needs_review to positive_review
Yes, that did it. Everything works now.
comment:16 Changed 5 years ago by
- Work issues docstring deleted
comment:17 Changed 5 years ago by
- Merged in set to sage-5.13.beta3
- Resolution set to fixed
- Status changed from positive_review to closed
It passed the doc test and the long test.
Functionality still works.
