%CHANGE(<num1>,<num2>)
This function calculates the percentage change moving from
X to Y using
the formula
100(Y-X)/X. It can be used to calculate (for example)
percentage profit and loss.
Eg. I buy a fridge for $400 and sell it for $440.
What is my profit as a percentage?
Use:
%CHANGE(400,440)
I sell a toy for $5.95 that normally sells for $6.50
What is the discount as a percentage of the usual price?
Use:
%CHANGE(6.50,5.95)

%, %TOTAL
%TOTAL(<num1>,<num2>)
To find out what percentage
X is of Y, use the function %TOTAL(Y,X).
Note the reversed order.
Eg. What percentage is a score of 53 out of 81 on a test?
Use:
%TOTAL(81,53)
What percentage is 124 of 112?
Use:
%TOTAL(112,124)
