In[1]:= x = {-1.25664, 0.628319, -0.628319, 1.25664,
Indeterminate, -1.25664, 0.628319, -0.628319, 1.25664,
Indeterminate};
Cases[x, _?NumericQ]

Out[2]= {-1.25664,0.628319,-0.628319,1.25664,-1.25664,0.628319,-0.628319, 1.25664}

In[3]:= x = Table[1/(3 - n), {n, 0, 5}];
Cases[x, _?NumericQ]

Out[4]= {1/3, 1/2, 1, -1, -(1/2)}
