All the digits are there as can be seen from:
In[1]:= ToExpression["1.23456789"]
Out[1]= 1.23457
In[2]:= RealDigits@%
Out[2]= {{1,2,3,4,5,6,7,8,9,0,0,0,0,0,0,0},1}
Mathematica is simply displaying the number of digits set by
your preferences. If you want Mathematica to display a different
number of digits, change your preferences appropriately.
