**Part 1 - The Formula**

Let's say you have the following two cells (B2 and B3, respecitvely):

```
3
4.3
```

`INT()`

will round a number down to the nearest integer.

When you run `=INT(B2)=B2`

, it evaluates the first part, `INT(B2)`

which will return simply `3`

. *Then* it checks is `3=3`

? Yes it does, so it returns `TRUE`

for the whole formula.

When you run `=INT(B3)=B3`

, it evaluates `INT(4.3)`

which returns the next whole number when rounding down, in this case `4`

.

Then it checks `4=4.3`

which returns `FALSE`

for the overall formula.

**Part 2 - The Referencing**

When you have the formula applied to the range `A2:D60`

(I'm assuming this is the "Applies To" range), you will be running the formula on ALL cells within that range.

If you removed the absolute references in the formula, the formula would evaluate on every cell in your range, regardless of column. in `C23`

the formula would be `=INT(C23)=C23`

. See below - the formula actually being run in that cell is `=INT(C2)=C2`

. Since `6.5`

is not an integer, it returns `FALSE`

and therefore no formatting is applied.

Since you want to check **only column B** for the integer, you need the absolute reference. That means on cell `C23`

, the formula being evaluated is `=INT($B23)=$B23`

.

The "Applies To" range will then apply whatever formatting you have - so if `B23`

is `10`

, then `A23:D23`

should have your formatting.
