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?
