Text truncation is the process of shortening the content of text. If the text is truncated, it is usually followed by three periods called an ellipsis. On web pages, there are several ways to shorten text content to fit within a given designated area. Truncation is a useful technique for making text fit into a particular space, such as a web page or a file pane.
Strings can also be truncated, which can be useful if a string exceeds the maximum character limit for a given application. A good way to understand the effects of a truncated sentence is to extend it by adding the missing words and comparing the extended version with the truncated one. Truncation error analysis provides a widely applicable framework for analyzing the accuracy of finite difference schemes. A truncation operation in code can take a number with several digits to the left of the decimal point and truncate that number into an integer.
On some occasions, there is a string list which includes some long strings, and for neatness you may want to truncate the strings to a fixed length.
