Midpoint Error Calculator

The Midpoint Error Calculator is designed to help determine the error in approximation methods, particularly in numerical analysis and interpolation. By calculating the midpoint between an actual value and its approximation, this tool gives insights into how closely the approximation matches the real value.

Formula

The midpoint error is calculated using the formula:

\[ \text{Midpoint Error} = \frac{\text{Actual Value} + \text{Approximation}}{2} - \text{Actual Value} \]

Example Calculation

If the actual value is 10 and the approximation is 12, the midpoint error is:

\[ \text{Midpoint} = \frac{10 + 12}{2} = 11 \]

\[ \text{Midpoint Error} = 11 - 10 = 1 \]

Importance and Usage Scenarios

This calculator is useful for evaluating the precision of approximations in numerical methods like interpolation, integration, or solving differential equations.
