TRUNC

The TRUNC functions truncates a number based on the number of decimal places specified in the second parameter.

By default, the TRUNC() function allows you to remove all digits to the right of the decimal point without applying rounding. If a second optional parameter is added to the TRUNC() function, it defines the number of digits to the right of the decimal point at which truncation is applied. Negative values are supported for the second parameter.

  • The first input value can be any constant, fact, metric, or metric expression.
  • The optional second parameter defines the number of decimal points at which the remaining digits are removed. This parameter should be an integer, although real numbers are supported for input.

Syntax

SELECT TRUNC(…)
TRUNC(constant)
TRUNC(fact)
TRUNC(metric)
TRUNC(metric_expression)
TRUNC(input, number_of_decimal_places)

Examples

SELECT TRUNC(12.2) = 12
SELECT TRUNC(12.7) = 12
SELECT TRUNC(12.257,2) = 12.25
SELECT TRUNC(1255.257,-2) = 1200
