Hello,
I just have discovered some strange (buggy?) feature of ArcTan[]
function in Mathematica 5.2. Try the following;
In[72]:=
ArcTan[.5,$MachinePrecision]
ArcTan[.5]
Out[72]=
1.53947
Out[73]=
0.463648
The expression ArcTan[.5,$MachinePrecision] must (?) give an error but
in really gives some strange output without any error messages... What
do you think about this?
