For your information: Code Complete has a chapter decicated to variable naming.

In your example one problem is that the member variable in Foo is not very descriptive to start with, which makes it hard to find a useful name for the placeholder local variable.

For example, I would do something like this:

struct Foo
{
  double mValue; // I don't use underscores here
                 // however, you can do as you please.
                 // Also 'mValue' is just for the sake of example,
                 // you should find a more descriptive name :D

};


void function (Foo* f)
{
   double oldValue = f->mValue;

       /***Other stuff***/

   f->mValue = oldValue;
}
