The INT Excel function rounds a decimal number down to the nearest integer and returns it. It is one of the rounding functions in Excel which returns a positive or negative integer as an output.

The INT function returns the integer 3 for the number 3.6. When we use the function on -3.6, it returns an integer away from zero, that is, -4.
