By definition of percent error, you can't. But you can approximate zero instead, with the number of decimals appropriate to the accuracy of the measurement, e.g. 0.01, 1E-100, etc.

What is the absolute error for 56 - 0.70?
55.3
What makes your percent error calculated value not equal to the actual value?
You do not add the percentage error but the actual error.
What is mean absolute percentage error?
The mean absolute percent prediction error (MAPE), .The summation ignores observations where yt = 0.
How do you calculate percentage error?
It is your estimate minus the true value divided by the true value and multiplied by 100. So, % error = (estimate - actual) / actual * 100, in absolute value. For example, if you estimate that there are 90 jelly beans in a jar when there are actually 130 your percentage error is: (90-130)/130 * 100 = -40/130 * 100 = -0.308*100 = -30.8% After absolute value, the answer is simply 30.769, or 30.8%.
What is the percent of error of 2.5?
2.5% error. Hence, theoritical - 2.5% = actual.
IF The weight of a rock is measured at 2.5 pounds what is the percent error in this measurement?
The percent error is calculated by taking the absolute difference between the measured value and actual value, dividing it by the actual value, and then multiplying by 100. If the actual weight is not provided, the percent error cannot be calculated.
What is the absolute error for 56 - 0.70?
55.3
What is a high percent error mean?
high percent error is the absolute value of something that is multiplied
What does it mean if you get a negative number when you calculate for percent error?
Depending on whether you subtract actual value from expected value or other way around, a positive or negative percent error, will tell you on which side of the expected value that your actual value is. For example, suppose your expected value is 24, and your actual value is 24.3 then if you do the following calculation to figure percent error:[percent error] = (actual value - expected value)/(actual value) - 1 --> then convert to percent.So you have (24.3 - 24)/24 -1 = .0125 --> 1.25%, which tells me the actual is higher than the expected. If instead, you subtracted the actual from the expected, then you would get a negative 1.25%, but your actual is still greater than the expected. My preference is to subtract the expected from the actual. That way a positive error tells you the actual is greater than expected, and a negative percent error tells you that the actual is less than the expected.

Formula for percent error?
Percent Error = {Absolute value (Experimental value - Theoretical Value) / Theoretical Value }*100
Absolute percent error?
Absolute percent error is the Percent Difference between two values.Applying the equation for Absolute error.For example: 21.571 is the True value 20.000 is the Recorded Value.Thus: (Recorded Value) - (True value) = Absolute error (21.571) - (20.000) = 1.571We modify this to match the following:(Recorded Value ) - (True value) / True value * 100This will give us a percent error of:(20.000 - 21.571) / 21.571 *100 = -7.28%
What is the measured the density of Copper to be 68.7 gcm3 The accepted density of Copper is 63.5 gcm3 What was your percent error?
To calculate percent error, we can use the formula: Percent Error = [(Measured Value - Accepted Value) / Accepted Value] x 100. Plugging in the values: Percent Error = [(68.7 - 63.5) / 63.5] x 100 = (5.2 / 63.5) x 100 = 0.082 x 100 = 8.2%.
How do you show percent error?
Percent error = (actual value - theoretical value) / theoretical value * 100%

2.5% error. Hence, theoritical - 2.5% = actual.
