In mathematics and computer science, truncation is the process of limiting the number of digits to the right of the decimal point. When **truncating** a number, we find an estimate of the number without rounding. To truncate a number, we omit digits beyond a certain point in the number, padding zeros if necessary so that the **truncated** number is approximately the same size as the original number. In simpler terms, **truncating** means cutting off the decimal part of a number.

Truncation is often used in reference to types of data or variables, such as floating point numbers and strings. Truncation consists of shortening a number by a given place value and filling in any zero to keep the same size. When information is sent or saved, programs may truncate data to the first 255 characters. Truncates (cuts) the dot and the digits to its right, regardless of whether the argument is a positive or negative number.

Truncation is a method of approximating a decimal number by removing all decimals beyond a given point without rounding. Truncation worksheets are available based on questions from Edexcel, AQA, and OCR exams. Syntax · Table truncation arguments remove all rows from a table, except for the table structure and its columns, constraints, indexes, etc. You can also truncate physical things by cutting them down to their stumps. Strings can be truncated if they exceed the maximum character limit for a given application.

To truncate a number to 3 significant digits, omit all digits after the first three significant digits (the first non-zero digit and the next two digits). 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. For example, a function can truncate the decimal part of a floating-point number to convert it to an integer. To truncate a polynomial P to degree n can be defined as the sum of all P terms of degree n or less. You can also truncate something by removing its beginning, end, top, or other part.
