Re: Limit of Floor function

Hi,

Limit[Floor[x], x->10] is a one-sided limit. The Direction option is set to Automatic by default, which means Direction->-1 (from the right) except when the limit point is Infinity. Here's another example:

In[1]:= Limit[1/x, x->0]

Out[1]= Infinity

In[2]:= Limit[1/x, x->0, Direction->#]& /@ {-1, 1}

Out[2]= {Infinity, -Infinity}

Bhuvanesh,
