TRUNCNUM function [Numeric]

Truncates a number at a specified number of places after the decimal point.

Syntax
{ TRUNCNUM | "TRUNCATE" }( numeric-expression, integer-expression )
Parameters
  • 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.

Remarks

You should use the TRUNCNUM function, not the TRUNCATE function, when truncating numbers.

Use of the TRUNCATE statement is not recommended because the word truncate is a keyword, and therefore requires you to either set the quoted_identifier option to OFF, or put quotes around the word TRUNCATE.
