Hello! I'm using Mathematica 9.0.0.0 and I've come across following puzzling results:
In[12]:= Log[8.62096/8.62096]
Log[8.62097/8.62097]
Log[8.62098/8.62098]
Out[12]= 0.
Out[13]= -1.11022*10^-16
Out[14]= 0.
When I calculate logarithm of quotient of two equal numbers I do not always get zero. What might be the reason for that?
