Truncation vs roundoff error
WebJul 25, 2014 · Truncation Errors • Truncation errors are those that result from using an approximation in place of an exact mathematical procedure. • Example 1: approximation to a derivative using a finite-difference equation:Example 2: The Taylor Series. The Taylor Theorem and Series • The Taylor theorem states that any smooth function can be ... Webcomponents. For this reason errors due to computing, or so-called numerical errors are tolerable if they do not exceed the effects of these built-in errors. Reduction of numerical errors occurs at the expense of increased computing effort (increased CPU time). More accurate computations are more expensive.
