Summary
| Description |
English: Difference in root of quadratic equation using Excel. x^2 + b x + c = 0 as a function of b for two values of c; the direct evaluation of the quadratic formula is compared with the approximation for widely spaced roots, which doesn't have a round-off problem. The squiggly behavior at large b-values is round-off noise. |

This graph image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with
{{vector version available|new image name}}.
It is recommended to name the SVG file “Excel quadratic error.svg”—then the template Vector version available (or Vva) does not need the new image name parameter. |
