Day 3 - int vs. float vs. double

There are situations when a doesn't have to be integer.
Uff! I 'll have to change the preveous type int to float.
But float is not good, it's to small.
Let it be double.

And now it looks like this:
 class MyClass
    MyClass( double P_a ): M_a( P_a ){}

	void clac(){ std::cout << "Do not disturb! calc in progress ..." << std::endl; }

    double a;
I did well this time.
Another minor change.
And it all began at char-a.
