Rounds a number down to the nearest integer.
The number you want to round down to an integer
A whole 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 lower number.
The following expression rounds the value to 1. If you use the ROUND function, the result would be 2.
