#12967: comparison of pi and infinity wrong
-------------------------+--------------------------------------------------
Reporter: dkrenn | Owner: burcin

We have
{{{
sage: bool(pi<Infinity)
False
sage: bool(pi>Infinity)
True
}}}
which is obviously wrong. It seems that the problem only occurs with
{{{pi}}}, because the following give correct results
{{{
sage: bool(pi<2*pi)
True
sage: bool(2*pi<Infinity)
True
sage: bool(e<Infinity)
True
sage: bool(e<pi)
True
}}}
