21. The first graph in this section shows the relative error vs ., for 1 through all 5 terms listed above. 22. Neglecting the virtual temperature correction may result in substantial relative errors in the calculated value of CAPE for small CAPE values. 23. For a number system and a rounding procedure, machine epsilon is the maximum relative error of the chosen rounding procedure. 24. Firstly, relative error is undefined when the true value is zero as it appears in the denominator ( see below ). 25. The system is very lax with rounding and accepts any answer as long as the relative error is below a few percent. 26. The relative error in T is larger than might be reasonable so that the effect of the bias can be more clearly seen. 27. In exact terms the power ratio is 10, or about 3.9811, a relative error of about 0.5 %. 28. Instead, the theorem states that } } approximates in the sense that the relative error of this approximation approaches 0 as increases without bound. 29. Lattice parameters of high accuracy can in fact be obtained from electron diffraction, relative errors less than 0.1 % have been demonstrated. 30. The denominator in the relative error is the number being rounded, which should be as small as possible to make the relative error large.
