** this is not a bug report *** Windows 3.0.0.0. hi all, it was a surprise to find : In[ ]:= Table[Round[LogGamma[n]/Log[4]],{n,24}] \!\($MaxExtraPrecision::"meprec" \( : \ \) "In attempting to evaluate \!\(Round[\(\(Log[2]\)\/\(Log[4]\)\)]\), \ $MaxExtraPrecision \!\(50.`\) was encountered. Increasing the value of \ $MaxExtraPrecision may help resolve the uncertainty."\) Out[8]= \!\({0, 0, Round[Log[2]\/Log[4]], 1, 2, 3, 5, 6, 8, 9, 11, 13, 14, 16, 18, 20, 22, 24, 26, 28, 31, 33, 35, 37}\) and : In[12]:=Log[2]/Log[4] Out[12]=\!\(Log[2]\/Log[4]\) In[13]:=Log[2]/Log[4] // Simplify Out[13]=\!\(Log[2]\/Log[4]\) In[14]:=Log[2]/Log[4] //FullSimplify Out[14]=\!\(1\/2\) Of course al this is correct ! But shouldn't it be trapped by the internal routines without causing 'blue fuss' ? wouter. ----------------------- EulerPhi[1] should be 1, not 0. ----------------------- Dr. Wouter L. J.
