To find the real value in relative error, you first need to determine the absolute error, which is the difference between the measured value and the true value. The relative error is then calculated by dividing the absolute error by the true value, often expressed as a percentage by multiplying by 100. The formula is: ( \text{Relative Error} = \frac{|\text{Measured Value} - \text{True Value}|}{|\text{True Value}|} \times 100). This gives you a sense of how significant the error is compared to the true value.

What does relative error percentage mean?
Relative error percentage is a decimal percentage between 1 and 0 such that if you multiply the actual answer by (1-errorrel) you get your approximate value. In other words relative error is an indicator of how far away your apporximation is from the real value in terms of percent of the real value.
What does it mean to have a high percentage error?
It means that, relative to the true value of whatever you are trying to measure, the estimated (or calculated) value is quite a long way off.If the real value of something is 5 but is measure as 7 the absolute error is 7 - 5 = 2, but the percentage error is 100*2/5 = 40%If the true value is 100 and it is measured as 103, the absolute error is 103 - 100 = 3 which is greater than before. But the percentage error is only 100*3/100 = 3%.
What does negative percentage error indicate?
In a numerical analysis sense, it means you've made a mistake/forgotten to take the modulus, as the formula for error calculation involves taking modulus values:Erel= |x-x*| / |x|, where x is the proper value, and x* an approximate value.Percentage error is just the relative error (formula above) x100, so really if you calculate it correctly, its actually impossible to get a negative percentage error.That aside, the only thing a negative error means, besides making a mistake, is that your approximation is larger/smaller than the real value, depending on which one you take away from, as it doesn't matter if you do x-x* or x*-x due to the modulus. The only thing that matters about any error value, is the size/number, which indicates by how much your approximation differs from the real value.
What type of error will occur when a real value is attempted to be assigned to an integer variable?
When a real value is assigned to an integer variable, a type error can occur, leading to potential data loss or truncation of the decimal part. In programming languages that enforce strict type checking, this operation may result in a compilation error or runtime error. In languages with implicit type conversion, the real value may be truncated to fit the integer type, discarding any fractional component.

What error occurs when a real value is attempted to be assigned to an integer variable?
real value neededA compile time error i.e ..Error: possible loss of precision: double, required: intNone, it will converted automagically.
How you would determine how much error there is between a vector addition and the real results?
To determine the error between a vector addition and the real results, you would subtract the calculated vector addition from the real vector addition. This difference will provide you with the error value. The error value can then be analyzed to understand the accuracy of the vector addition calculation.
How are you to assess the relative goodness or value of situations?
By comparison to similar situations, real or hypothetical.

What is systematic error?
Such an error is a recurring error because of a faulty measuring instrument or some recurring experimental condition that distorts the data every time a measurement is made.

What is forecast error?
In statistics, a forecast error is the difference between the actual or real and the predicted or forecast value of a time series or any other phenomenon of interest.
What is the rotation period of earth measured relative to the sun?
24 hours. Relative to the stars (the "real rotation"), it is about 23h56m.24 hours. Relative to the stars (the "real rotation"), it is about 23h56m.24 hours. Relative to the stars (the "real rotation"), it is about 23h56m.24 hours. Relative to the stars (the "real rotation"), it is about 23h56m.

What is the formula to find maximum percentage error between measured and real values of resistor?
From what I can remember it's: |R(measured)-R(real)|/(R(real))*100%
