An interesting (or possibly not) question came up as some colleagues and I were discussing % growth.

The logic flows thusly:

A = previous total

B = new total.

Simple % growth = (B - A)/ A.

So, if we had 100 widgets in March and 150 widgets in April, that with by a 50% growth (150 - 100)/100 =.50.

So how do you define it, if at all, if you start from zero.

You’ve got 0 widgets in February and now you’ve got 100 widgets in March. What’s the % growth? Can’t divide by zero. Undefinable?
