Percent error calculation

The absolute error is equal to the absolute value of the difference between the exact value and the approximated value:

ε = | Vexact - Vapprox |

The percent error is equal to the 100% times the absolute error divided by the exact value:

δ = 100% × | Vexact - Vapprox | / | Vexact |
