P is the percentage, V 1 is the first value that the percentage will modify, and V 2 is the result of the percentage operating on V 1. The calculator provided automatically converts the input percentage into a decimal to compute the solution. However, if solving for the percentage, the value returned will be the actual percentage, not its decimal representation.
If solving manually, the formula requires the percentage in decimal form, so the solution for P needs to be multiplied by in order to convert it to a percent. This is essentially what the calculator above does, except that it accepts inputs in percent rather than decimal form. The percentage difference between two values is calculated by dividing the absolute value of the difference between two numbers by the average of those two numbers. Multiplying the result by will yield the solution in percent, rather than decimal form.
