Rounding and truncation are typical examples of quantization processes. This method minimizes the truncation error. This error is either due to rounding or truncation. This proposed processing includes filtering, histogram truncation and equalization steps. The definition of the global truncation error is also unchanged. The remainder term of a Taylor polynomial is convenient for analyzing the local truncation error. The above definitions are particularly relevant in situations where truncation errors are not important. Just take the log of a uniform random variable (with appropriate interval and corresponding truncation). Bit rate and the obtained quality are adjustable by simple bitstream truncation. The two common approaches to exclude outliers are truncation (or trimming) and Winsorising. An analogue of truncation can be applied to polynomials. There are aptamer applications for which a short sequence, and thus primer truncation, is desirable. This operation is known variously as the second truncation, degenerate truncation, or rectification. These improper regular tilings are constructionally related to prismatic uniform honeycombs by truncation operations. A right frustum is a parallel truncation of a right pyramid or right cone.
