Description (last modified by burcin)

The order in which the terms in some symbolic expressions are printed depends on the platform/system. For example, evaluating cos(x) + zeta(x) yields

  • zeta(x) + cos(x) on Linux
  • cos(x) + zeta(x) on OS X

in Sage 4.4.4 and 4.5.2.alpha{0,1}, at least.

Please see #9582 for some details and discussion.

#10282 is a duplicate of this issue.

The patches attached to #9880 fix this.

#10282 almost certainly is the same thing.

comment:3 Changed 11 years ago by kcrisman

When this is closed (which would hopefully happen with #9880 integrated), let's be sure to write doctests for both this ticket and #10282, which would just be to say that 

sage: psi(1,1/3)*log(3)
log(3)*psi(1, 1/3)

is the same on all systems, in addition to the zeta(x)+cos(x) example here.

This was fixed by #9880. trac_9632-doctests.patch​ adds doctests.
