Hi Developers, (sage 3.2.2 on a 32-bit Athlon running Debian etch) I would report it to trac (tell me if I should), but I'm not sure if it's a bug,
increasing precision of a complex number which has imaginary part zero results in a real number: this works: sage: a = CC(-5. + I*0.0001).n(prec=100) sage: type(a) <type 'sage.rings.complex_number.ComplexNumber'> sage: a.prec() 100 but here a turns into a real number: sage: a = CC(-5 + I*0.).n(prec=100) sage: type(a) <type 'sage.rings.real_mpfr.RealNumber'> sage: a.prec() 100 if this is a feature, than it's annoying, for example taking the logarithm of -5 with precision 100 than leads to sage: ln(CC(-5).n(prec=100)) NaN I know how to do it the right way (ln(ComplexField(100)(-5)), but the above should work too, or?
