TRUNC - Daxplained

TRUNC is a DAX function that truncates a number to an integer by removing its decimal part.

Syntax

TRUNC(
   Number,
   NumberOfDigits
)

Argument	Properties	Description
Number		The number you want to truncate.
NumberOfDigits	Optional	A number specifying the precision of the truncation; if omitted, 0 (zero).

Return Values

A whole number.

Remarks

TRUNC and INT are similar in that both return integers. TRUNC removes the fractional part of the number. INT rounds numbers down to the nearest integer based on the value of the fractional part of the number. INT and TRUNC are different only when using negative numbers: TRUNC(-4.3) returns -4, but INT(-4.3) returns -5 because -5 is the smaller number.

Example 1

The following formula returns 3, the integer part of pi.

= TRUNC(PI())

Example 2

The following formula returns -8, the integer part of -8.9.

= TRUNC(-8.9)
