## Basic logical test in Excel

In Excel, any logical test returns TRUE of FALSE.

For instance, to compare the contains of 2 columns, you have to write the following test.

=A2=B2

In this second example, we want to know if our customer have 21 years-old or more. So we create the following test with an absolute reference to the limit cell.

=B2>=$G$4

## How to convert the test to a numeric value?

So when you create a test in Excel, the result is TRUE or FALSE by default.

**Tips **💡And the result is always **displayed in the center of the cell**, ALWAYS 😉

But, you can convert TRUE or FALSE to 1 or 0 with 2 different method

## Method 1: Multiply by 1

The first method is to multiply the logical test by 1

=(logical test)*1

**You can see in column D the formula used**

## Method 2: Write 2 dashes

The other technique is to write **2 dashes before the test** like in this example.

=--(logical test)

And the result is the same; the test returns 0 or 1.
