André:

Realize that

In[1]:=
FullForm[N[Log[8]/Log[2]]]

Out[1]//FullForm=
2.9999999999999996`

Under these conditions, and keeping in mind that

In[2]:=
?Floor

In[2]:=
"Floor[x] gives the greatest integer less than or equal to x."

It is obvious that

In[3]:=
Floor[N[Log[8]/Log[2]]]

Out[3]=
2

In[4]:=
Ceiling[N[Log[8]/Log[2]]]

Out[4]=
3

Greetings,
