Excel INT Function

Summary

The Excel INT function returns the integer part of a decimal number by rounding down to the integer. Note the INT function rounds down, so negative numbers become more negative. For example, while INT(10.8) returns 10, INT(-10.8) returns -11.

Purpose

Get the integer part of a decimal by rounding down

Return value

The integer part of the number after rounding down

Syntax

=INT (number)

Arguments

number - The number from which you want an integer.

Usage notes

Use the INT function when you want only the integer part of a decimal number, and it's ok to always round the number down. For example, INT (3.99) returns the number 3.

It's important to note that INT actually rounds down numbers to the next lowest integer value.

So, while INT (10.8) = 10, INT(-10.8) = -11.

Use the TRUNC function if you want the exact integer part of both negative and positive numbers.
