How do I find the percent error if the theoretical value is 0?

The equation for % error is [absolute value(calculated value - theoretical value) / theoretical value] * 100, but 0 can't be in the denominator, because you can't divide by 0. So how would you calculate it?

    Just a thought. Use the value epsilon(a small number) as theoretical value, do your calculations based on this. I assume you are working with extremely small numbers (<0.001)

    You may add a number to both the values ie theoretical and observed value...for an example if your theoretical value is 0 and observed value is 2...By adding 1 for example on both sides and by applying it on formula (theoretical value-Observed value)/Theoretical Value X 100::::[(0+1)-(2+1)]/(0+1) x 100=200%....This adjustment can be called as Zero level adjustment.

    There is no percent error if the answer is zero. the only way to state the answer is: 0. +/- (absolute error)

    First, you're taking the adaptation of your fee and the fairly fee, 396.3-330 = sixty six.3 then you take that distinction and divide it by ability of the fairly fee : sixty six.3/330 = .20 so the % errors is 20% desire this helps :D
