A roundoff error, also called rounding error, is the difference between the result produced by a given algorithm using exact arithmetic and the result produced by the same algorithm using finite-precision, rounded arithmetic. Rounding errors are due to inexactness in the representation of real numbers and the arithmetic operations done with them. This is a form of quantization error. When using approximation equations or algorithms, especially when using finitely many digits to repres… Web2.3.2 Truncation Errors . Truncation Error: result from using numerical method (approximation) in place of an exact mathematical procedure to find the solution.
