Maybe I'm forgetting my grade school math here, but is there an
easier way to calculate the percentage difference between two numbers?
If I have two numbers, say:
5, 7
To calculate percentage I take the smaller and divide by the larger:
5/7 = .7142857
Then subract 1 = -.2857143
Get rid of the - sign and have .2857143 percent
Problem is this assumes I know which is smaller and which is larger.
Reversing the numbers doesn't work, i.e., 7/5 doesn't work at all. So
I have this AFL formula:
daypercent = iif(close > ref(close,-1), ref(close,-1) / close,
close / ref(close, -1));
Isn't there an easier math technique to figure the percentage between
2 numbers regardless of which is larger?
