Do you want a machine number or an extended precision number? If you 
want a machine number, then the result of ToExpression gives you what 
you want:

In[237]:= ToExpression["1.23456789"] // InputForm


If you want an extended precision number, you can add a tick:

In[238]:= ToExpression["1.23456789`9"]

Out[238]= 1.23456789
