The Floor function is very simple. It takes any real number (x) as input and provides the highest integer less than that real number as the output. For example, floor (0.85) is 0.

The beauty of the floor function is that it always gives you a discrete integer and never a fraction as its output. It can be very rewarding if your decision making for introducing new product features was comparable to the floor function where the input is restricted to the range [0,1], i.e. all real numbers from 0 through 1 including 0 and 1.

Thinking this way will force you to clearly define the impact the new feature will have on the users, and only when that impact is 1 will you actually go ahead and ship the feature, because anything less than 1 would mean that it has zero impact on the users.
