# What is Truncation in Digital Logic?

Truncation is an important tool used in digital logic and mathematics that helps limit the number of digits to the right of the decimal point. Learn more about what it is and how it works here.

Truncation is a powerful tool used in digital logic and mathematics to limit the number of digits to the right of the decimal point. It is also known as wildcard search, which allows you to search for a term and its spelling variants. Truncation is used in databases to broaden the search for keywords by attaching them to the root of a word, usually done by adding an asterisk (*) at the end of the root. In computer applications, truncation error is the discrepancy that arises from executing a finite number of steps to approach an infinite process.

Different databases use different truncation symbols, so it's important to check the “Help” information or “Search Tips” in the database for details on which symbol to use. Truncation is a useful technique for retrieving variant endings of words from databases. It can also be used to refine your search strategy, as it allows you to search for different forms of a word simultaneously and will increase the number of search results found. When information is sent or saved, programs may truncate data to the first 255 characters, with any excess digits trimmed (hence the truncated expression).

The truncation error is the difference between a truncated value and the actual value, or 0.00792458 x 108. Truncation of a polynomial P to degree n can be defined as the sum of all the terms of P of degree n or less. A number of operating systems or programming languages use truncate as a command or function to limit the size of a field, data flow, or file. In conclusion, truncation is an important tool used in digital logic and mathematics that helps limit the number of digits to the right of the decimal point. It is also used in databases to broaden searches for keywords by attaching them to the root of a word with an asterisk (*).

Truncation error is the discrepancy that arises from executing a finite number of steps to approach an infinite process. Different databases use different truncation symbols, so it's important to check the “Help” information or “Search Tips” in the database for details on which symbol to use.
