Theorem pnfnei 21232
Description: A neighborhood of +∞ contains an unbounded interval based at a real number. Together with xrtgioo 22816 (which describes neighborhoods of ) and mnfnei 21233, this gives all "negative" topological information ensuring that it is not too fine (and of course iooordt 21229 and similar ensure that it has all the sets we want). (Contributed by Mario Carneiro, 3-Sep-2015.)
