Sage 4.3.1 Release Tour

Major features

  • Substantial work towards a complete SPARC Solaris 10 port. This is due to the hard work of David Kirkby. The relevant tickets include #6595, #7138, #7162, #7505, #7817.

  • We're moving closer towards a FreeBSD port, thanks to the work of Peter Jeremy at ticket #7825.

Basic arithmetics

  • Implement conjugate() for RealDoubleElement #7834 (Dag Sverre Seljebotn) --- New method conjugate() in the class RealDoubleElement of the module sage/rings/real_double.pyx for returning the complex conjugate of a real number. This is consistent with conjugate() methods in ZZ and RR. For example,

    sage: ZZ(5).conjugate()
    5
    sage: RR(5).conjugate()
    5.00000000000000
    sage: RDF(5).conjugate()
    5.0
