If you want a machine number, then the result of ToExpression gives you what you want: In[237]:= ToExpression["1.23456789"] // InputForm Out[237]//InputForm= 1.23456789 If you want an extended precision number, you can add a tick: In[238]:= ToExpression["1.23456789`9"] Out[238]= 1.23456789 Carl Woll Wolfram Research
