Possible bug in Floor function?
Hi, I think I may have stumbled upon a possible bug in Floor. Evaluating the following gives the correct result: Floor[Log[10, 100.]] 2 Evaluating it with a replacement and //N gives a message and the wrong result: Floor[Log[10, x]] /. x -> 100 // N Floor::meprec: Internal precision limit $MaxExtraPrecision = 50.` reached while evaluating Floor[Log/Log]. >> 1 I'm on Math 9.0 + Win7, but Math 8 gives the same (wrong) result as well. Cheers
