![TRIM function [String]](arrow-left.gif){kind=icon}
![TRUNCNUM function [Numeric]](arrow-right.gif){kind=icon}
Truncates a number at a specified number of places after the decimal point. Deprecated in favor of TRUNCNUM.
"TRUNCATE" ( numeric-expression, integer-expression )
numeric-expression The number to be truncated.
integer-expression A positive integer specifies the number of significant digits to the right of the decimal point at which to round. A negative expression specifies the number of significant digits to the left of the decimal point at which to round.
The following statement returns the value 600:
SELECT "TRUNCATE"( 655, -2 ) FROM iq_dummy
The following statement returns the value 655.340:
SELECT "TRUNCATE"( 655.348, 2 ) FROM iq_dummy
This function is the same as TRUNCNUM. Using TRUNCNUM is recommended, as it does not cause keyword conflicts.
The quotation marks are required because of a keyword conflict with the TRUNCATE TABLE statement. You can use TRUNCATE without the quotation marks only if the QUOTED_IDENTIFIER option is set to OFF.
You can use combinations of ROUND, FLOOR, and CEILING to provide similar functionality.
