Fractions can be 15/7 or 767/5. Hardly communicating something small.

A "small fractional" change would be a linear change such as Y= nX where n is a constant such as 2/3. A geometric change would be Y= X^n. And an exponential change would be Y=n^X. These are 3 different types of changes with fundamentally different properties. Exponential change grows (positively or negatively depending on specifics) vastly faster than the other two and should not be confused.</font></div><div class="gmail_default" style=""><font size="4"><br></font></div><div class="gmail_default" style=""><font size="4">John K Clark</font></div>
