Hello everybody, I'm using Mathematica 5.1 under Win2k and I found a bug when I try to compute -3^49999. I get: -3^49999 //N => -3.85 * 10^23855 okay -3^49999. => -3.85 * 10^23855 okay (-3)^49999. => -3.85 * 10^23855 + 4.56*10^23844 i wrong (-3)^49999 => -3.85 * 10^23855 okay Is this a known problem? Is there a work around ? Obviously this is part of a more complicated calculation and so I cannot simply leave out the brackets. Many thanks, Axel
