Depends on which writer you ask. Grant Morrison, Alan Moore, and some others say he has unlimted power. Dan Jurgens however on Twitter says he has limits but very very very high ones. Most DC writers just make him as op as they need him to be for the specific story. This is why Grant Morrison made him Limitless because Grant usually mixes his stories with reality. According to Mircle Man in Final Crisis the book of infinite pages did have infinite pages the final chapter Ultraman read was not the books final chapter but in fact the ending chapter to the Multiverse which happens at the end of Final Crisis.
