You can change exact numbers to machine precision (approximate)
numbers by using the built-in function N. But there is no way to
change a symbol to an approximate number until after a number
has been assigned to it.

I've no idea if the above is helpful to you or not. But it is
unlikely you are going to get any more helpful/meaningful
answers until you post details of the problem you are trying to
solve, preferably with Mathematica code.
