### Example 1: Format a Date (Bill Date)

* Double-click your newly created expression to insert it into the script editor.
* Define the expression using the syntax:
* Expression Name = FORMAT(CDATE(BILL\_DATE),"dd MMMMM yyyy")
  * `Format` Start your Expression with `Format` Keyword that is used to apply styles in Date & Text.
  * `CDate(BILL_DATE)` converts the value to a date.
  * `"dd-MMMM-yyyy"` is the desired date format.

<figure><img src="/files/01zqtIAH9JUwKy4jrZR5" alt=""><figcaption></figcaption></figure>

* Double-click your newly created expression to insert it into the script editor.
* Define the expression using the syntax:
  * Expression Name = FORMAT(RATE\_UNIT,"#0.00")
    * `RATE` is the numeric field name.
    * `"#0.00"` ensures **two decimal places**.

> To format with 4 decimal places: `Format(RATE, "#0.0000")`

<figure><img src="/files/4hOKVerisEJkGjqNcbKQ" alt=""><figcaption></figcaption></figure>

* Save the expression once defined.
* Scroll down and **check the box** beside the expression name to enable it.

* Save and proceed to check the effect.
* **Refresh the report** to view the final result.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://kb.logicerp.com/logic-erp-learning-hub-tutorials-and-best-practices/defining-custom-columns-in-reports-and-grids-with-expressions/format-function.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
