Pynac-0.3.3 will sync to current GiNaC which has a few consequences in the doctests. Before releasing 0.3.3 it might be good to look at potential changes, in order to check if they fit into Sage (and possibly revert them before release of 0.3.3).
The following changed behaviour leads to a few fails: sage: a,b = var('a b') sage: abs(sqrt(x)) sqrt(abs(x)) sage: sqrt(abs(x)^2) sqrt(x*conjugate(x)) sage: abs(x)^2 x*conjugate(x) sage: A = abs((a+I*b))^2 sage: A (a + I*b)*(conjugate(a) - I*conjugate(b)) sage: A.canonicalize_radical() a^2 + b^2 sage: imag(A) 0 sage: imag(A.canonicalize_radical()) 2*imag_part(a)*real_part(a) + 2*imag_part(b)*real_part(b) sage: f = sqrt(abs(x)^2); f.canonicalize_radical() x Reason is probably these commits: https://github.com/pynac/pynac/commit/b645d3c200e74531f735d786259d043cbffe758a https://github.com/pynac/pynac/commit/565d0c3307b708cc266d27d3d1344e6de9fbc513 So, do we want this? -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
