I think you did nothing wrong -- it should work the way you did it. Here is a work around: sage: R. = CC[] sage: I = x*R sage: J = y*R sage: singular(I).intersect(J) x*y That uses another Singular interface (not a C-library). The result lives there, so, you need to pull it back into your ring R: sage: parent(singular(I).intersect(J)) Singular sage: R*list(singular(I).intersect(J)) Ideal (x*y) of Multivariate Polynomial Ring in x, y over Complex Field with 53 bits of precision The second best solution is to work with a base ring that is supported by libSingular: sage: R. = ZZ[] sage: I = x*R sage: J = y*R sage: I.intersection(J) Ideal (-x*y) of Multivariate Polynomial Ring in x, y over Integer Ring sage: R. = QQ[] sage: I = x*R sage: J = y*R sage: I.intersection(J) Ideal (x*y) of Multivariate Polynomial Ring in x, y over Rational Field Of course, the best solution would be to wrap Singular's complex coefficients in libSingular.

[sage-support] Re: Intersection of complex Ideals
Singular supports working with floating-point complex numbers (CDF in Sage), so it should work. Having said that, floating-point computations with polynomials are often dangerous because of the limited precision. Its usually better to work with arbitrary-precision coefficients like QQ or cyclotomic numbers... sage: R.=QQ[] sage: R.ideal(x).intersection(R.ideal(y)) Ideal (x*y) of Multivariate Polynomial Ring in x, y over Rational Field -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
[sage-support] Intersection of complex Ideals
Dear all, Firstly I am using sage 4.6 on a ubunut machine. I have 2 ideals over the complex field and I would like to take their intersection. If I try and use the intersection method on one of the ideals i get an error message from singular stating the following type error: TypeError: Cannot call Singular function 'intersect' with ring parameter of type '' This was generated by the code: R. = PolynomialRing(CC, 2) I = x*R J = y*R I.intersection(J) The documentation doesnt say anything about not being able to take intersections over the complex field. Am I doing something wrong? Would anyone suggest a better way of doing this computation? Thank you for any comments.

[sage-support] Re: New to sage: significant digits, etc.
Thanks. Looks needlessly complicated. I did see significant errors crop up when I tried use .n(4) etc. So, your warning is pretty wise. Is there a way to extract the mantissa from a number (in base 10 - I do know that sign_mantissa_exponent() does it in base 2, which is not terribly useful). Alternatively, is there support for printf formats (C) ?

[sage-support] Accessing R documentation trough notebook broken with 4.6.1?
Hello, today I noticed that I cannot access R docs trough notebook, while it still works like usual from command line. This is what is inside notebook when viewed as text: sage: r.lm? Traceback (most recent call last): File "", line 1, in File "_sage_input_3.py", line 10, in exec compile(u'print _support_.docstring("r.lm", globals(), system="sage")' + '\n', '', 'single') File "", line 1, in File "/opt/sage/devel/sagenb/sagenb/misc/support.py", line 263, in docstring return html_markup(s) File "/opt/sage/devel/sagenb/sagenb/misc/support.py", line 288, in html_markup return '' + preamble + '' + s + '' UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 116: ordinal not in range(128) Currently I don't have alpha of newer version, so I wanted to ask if this is still visible with 4.6.2 versions and/or known issue. I've looked trough track and found few similar issues related to for example unicode handling in %latex, but not this particular.
