Mathematica by default does not display all of the digits in a machine precision number. For example, In[1]:= x = RandomReal[] Out[1]= 0.436287 In[2]:= RealDigits[x] Out[2]= {{4,3,6,2,8,7,3,0,2,4,3,3,0,6,3,1},0} Here the value returned by RandomReal has 16 significant digits but only 6 are displayed. My guess is all of the digits in your file have been read.
