The TRUNC function comes to mind. Indeed, if you look up the SAS TRUNC function, you will find that it does truncate numeric values, but (surprise!) not to a specified number of decimal places; rather it truncates to a specified number of bytes, which is not the same thing for numerics.

Moreover, how do you truncate in SAS?

The TRUNC function truncates a full-length number (stored as a double) to a smaller number of bytes, as specified in length and pads the truncated bytes with 0s. The truncation and subsequent expansion duplicate the effect of storing numbers in less than full length and then reading them.

Subsequently, question is, how do you round a number in SAS? ROUND is the function name; argument is the numeric value or variable you want to have rounded; and rounding-unit is the unit that you want to result to be rounded to (e.g. 10, 100, 0.1, 0.01, 5, etc.) For example, ROUND(34.58, 0.1) tells SAS to round the number 34.58 to the nearest tenth. SAS will return 34.6.

Likewise, how do you truncate a number?

To truncate a number, we miss off digits past a certain point in the number, filling-in zeros if necessary to make the truncated number approximately the same size as the original number. To truncate a number to 1 decimal place, miss off all the digits after the first decimal place.

What does truncation mean?

1. To shorten or reduce: The script was truncated to leave time for commercials. See Synonyms at shorten. 2. To shorten (a number) by dropping one or more digits after the decimal point.

## What is a truncate number?

Truncating a Number. A method of approximating a decimal number by dropping all decimal places past a certain point without rounding. For example, 3.14159265 can be truncated to 3.1415. Note: If 3.14159265were rounded to the same decimal place, the approximation would be 3.1416.

## What is a truncation symbol?

Truncation is a searching technique used in databases in which a word ending is replaced by a symbol. Frequently used truncation symbols include the asterisk (*), a question mark (?) or a dollar sign (\$).

## How do I truncate a word?

To truncate a search term, do a keyword search in a database, but remove the ending of the word and add an asterisk (*) to the end of the word. The database will retrieve results that include every word that begins with the letters you entered.

## What is truncate Excel?

Shorten digits and other worksheet data

To truncate means to shorten an object by cutting it off abruptly. In spreadsheet programs such as Microsoft Excel and Google Spreadsheets, both number data is truncated with your worksheet using the TRUNC function, while text is truncated using the RIGHT or LEFT function.

## How do I truncate a double?

If you need decimal places, use a BigDecimal , which has a setScale() method for truncation, or use DecimalFormat to get a String . If, for whatever reason, you don't want to use a BigDecimal you can cast your double to an int to truncate it. If you want to truncate to the Ones place: simply cast to int.

## What does math truncate do?

Truncate() is a math class method which is used to compute an integral part of a specified decimal number or double-precision floating-point number. This method can be overloaded by passing the different type of parameters to it as follows: Math. Truncate(Decimal) Math.

## How do I scan a function in SAS?

The SCAN function in SAS provides a simple and convenient way to parse out words from character strings.

The SCAN function in SAS

1. Selecting the nth word in a character string.
2. Selecting the last word in a character string.
3. Handling different word delimiters.
4. Using SCAN with DO LOOPs to parse long character strings.
