TRUNC Function (DAX)
Truncates a number to an integer by removing the decimal, or fractional, part of the number.
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.
