Calculating the percentage error provides a means to quantify the degree by which a measured value varies relative to the true value. A small percentage error means that the observed and true value are close while a large percentage error indicates that the observed and true value vary greatly. See more Percentage error is a measurement of the discrepancy between an observed (measured) and a true (expected, accepted, known etc.) value. It is typically used to … See more The computation of percentage error involves the use of the absolute error, which is simply the difference between the observed and the true value. The absolute … See more Based on the formula above, when the true value is positive, percentage error is always positive due to the absolute value. In most cases, only the error is … See more WebThe inaccuracy in Excel calculations is more complicated than errors due to a precision of 15 significant figures.

The result will be exact until you overflow the mantissa, because 0.25 is 1/ (2^2). Then try the same thing with 0.2 and you will get the problems, because 0.2 isn't representable in a finite base-2 number. industrias acre
