Excel INT Function

The INT function is used to round a number downwards towards the next lowest number.

INT is similar to the ROUNDDOWN function except that it always rounds a number down to the nearest whole number - completely removing the decimal portion.

The ROUNDDOWN function, on the other hand, will round a number down to a desired number of decimal places.

The syntax for the INT function is:

= INT ( Number)

Number - the value to be rounded. This can also be a cell reference to the location of the number in the spreadsheet.
