# true

Learn how to use the Boolean constant true in Notion formulas.
The `true` constant represents the Boolean output `true`. Its opposite is false.
1
true
Type `true` into a Notion formula property, and that property will output a checked checkbox, representing the value `true`.
A Boolean value has only two states, which can be thought of as:
• True or False
• 1 or 0
• On or Off
A Boolean simply represents the two truth values of logic.
Notion represents Boolean values with checked (true) and unchecked (false) checkboxes.
These resources aren’t necessary for understanding how to work with Booleans in Notion, but you may find them interesting if you want to dive deeper into how Booleans are used in programming and computer science.

## Example Formulas

This formula will simply output `true` in a Notion formula property, displaying as a checked checkbox:
1
true
Here’s a slightly more complex example formula that uses Notion’s if function:
1
true ? "😀" : "😭"
This is an `if()` statement written in shorthand - it could also be written as `if(true,"😀","😭")`. It will simply output 😀 if the condition is true. The condition is the first part of the `if()` statement, or what is left of the `?` in the shorthand formula.
Since the Boolean `true` outputs `true` naturally, the result will be 😀. See the Happy property in the example database below for proof.

## Example Database

`true` and `false` are case-sensitive. Typing `True` or `False` will result in a syntax error.
Here you can see how Notion displays `true` and `false` Boolean values. You can also see the output of our Happy formula, which is shown above.
