Burcin's status report for SD 12

pynac

  • print higher degree terms first
  • added:
    • support for symbolic binomial and factorial

    • .latex() method

    • .collect_common_factors()

    • iterators and __getitem__

    • .function() method to allow creating CallableSymbolicExpressions with pynac expressions

Changes above will be in the pynac-0.1.2 release, which should be released with Sage 3.3.

I have patches that

  • add constants for Infinity and UnsignedInfinity (to pynac)

  • implement arithmetic with infinity
  • make 1/gamma(-1) = 0
  • fix series expansion of 1/(1/sqrt(x) + 1/x)

which need to be cleaned up and tested more. They should be available for testing before I get home (next Tuesday).

bugs fixed

  • #4981 clean up polynomial_ring.py
  • #4840 FLINT: call the stack cleanup function at exit

reviews

  • 4850 bug in power_mod
  • 5027 comparing complex i raises error
  • 2957 Singular multivariate polynomials are buggy on exponent overflow)
