New issue 1815 by smichr: shift operator http://code.google.com/p/sympy/issues/detail?id=1815 In discussion http://groups.google.com/group/sympy/browse_thread/thread/214eaae150fc08a/e91b563a8ce01347?lnk=gst&q=shift+operator#e91b563a8ce01347 there was raised the issue of &, >> and << being overidden in sympy. Ondrej had thought it better that this were not the case. As of today I wish that it were not the case.
S(4)>>3
Implies(4, 3)
4>>3
0
S(4)&3
And(3, 4)
4&3
0 On the other hand, if the sympy objects are just un-sympified, i.e. if you just convert them back to integers (rather than Integers) then as you can see above, all is fine. Does anyone have strong feelings about this syntax being customized to sympy rather than having standard pythonic meaning? Should a test be done with these operators to see if the operands are Integers and then treat them as integers? /c -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
