Truncation, also known as derivation or wildcard search, is a technique used to broaden the scope of a search. It involves entering the root of a word and adding a truncation symbol at the end. This will return results that include any endings of that root word. For example, if you wanted to search for words that end in ‘tion’, you would enter ‘tion$’ into the search bar.
This would return results such as ‘action’, ‘caution’, and ‘option’. Truncation can also be used to easily truncate a positive value. To do this, simply subtract 0.5 from the value and then round it. This will give you the truncated value. Truncation is a useful tool for finding multiple variations of a word quickly and easily.
It can be used in many different contexts, from searching for words in a database to truncating values in mathematics.
