    TRUNCATE

    Rounds the input expression down the nearest of equal integer depending on the specified number of places before or after the decimal point.

    Syntax

    TRUNCATE(numeric_expression float) → int

    • numeric_expression: The numeric expression to truncate.

    Examples

    TRUNCATE example 
    SELECT TRUNCATE(987.65)
-- 987

    TRUNCATE(numeric_expression double) → int

    • numeric_expression: The numeric expression to truncate.

    Examples

    TRUNCATE example 
    SELECT TRUNCATE(987.87)
-- 987

    TRUNCATE(numeric_expression int32) → int32

    • numeric_expression: The numeric expression to truncate.

    Examples

    TRUNCATE example 
    SELECT TRUNCATE(2021)
-- 2021

    TRUNCATE(numeric_expression int64) → int64

    • numeric_expression: The numeric expression to truncate.

    Examples

    TRUNCATE example 
    SELECT TRUNCATE(2021)
-- 2021

    TRUNCATE(numeric_expression decimal(0,0), scale_expression int32) → decimal(0,0)

    • numeric_expression: The numeric expression to truncate.
    • scale_expression: sample parameter description

    Examples

    TRUNCATE example 
    SELECT TRUNCATE(89.2283211, 2)
-- 89.22

    TRUNCATE(numeric_expression int64, scale_expression int32) → int64

    • numeric_expression: The numeric expression to truncate.
    • scale_expression: sample parameter description

    Examples

    TRUNCATE example 
    SELECT TRUNCATE(2021, -1)
-- 2020

    TRUNCATE(numeric_expression decimal(0,0)) → decimal(0,0)

    • numeric_expression: The numeric expression to truncate.

    Examples

    TRUNCATE example 
    SELECT TRUNCATE(9.7)
-- 9

    TRUNCATE(numeric_expression float, scale_expression int32) → float

    • numeric_expression: The numeric expression to truncate.
    • scale_expression: The decimal place to round to.

    Examples

    TRUNCATE example 
    SELECT TRUNCATE(78.9823, 2)
-- 78.98

    TRUNCATE(numeric_expression int32, scale_expression int32) → int32

    • numeric_expression: The numeric expression to truncate.
    • scale_expression: The decimal place to round to.

    Examples

    TRUNCATE example 
    SELECT TRUNCATE(4356, -2)
-- 4300

    TRUNCATE(numeric_expression double, scale_expression int32) → double

    • numeric_expression: The numeric expression to truncate.
    • scale_expression: The decimal place to round to.

    Examples

    TRUNCATE example 
    SELECT TRUNCATE(987.65, 1)
-- 987.6

    Usage Notes

    To round to a place after the decimal point, specify the position as a positive number. To round to a place before the decimal point, specify the position as a negative number. To round to the nearest whole number, specify 0. If no decimal position is specified, then the function rounds to the nearest whole number (assumes 0 as the scale expression).
