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.
