## Method Signature

```
FormatBaseN(number=[numeric], radix=[integerTruncate])
```

### Arguments

| Argument | Type              | Required | Description | Default |
| -------- | ----------------- | -------- | ----------- | ------- |
| `number` | `numeric`         | `true`   |             |         |
| `radix`  | `integerTruncate` | `true`   |             |         |

## Examples

### Format 10 as dual number

[Run Example](https://try.boxlang.io/?code=eJxLyy%2FKTSxxSixO9dNQMDTQUTBS0LTmAgBU9gYI)

```java
formatBaseN( 10, 2 );

```

Result: 1010

### Format 1024 as hexadecimal number

[Run Example](https://try.boxlang.io/?code=eJxLyy%2FKTSxxSixO9dNQMDQwMtFRMDRT0LTmAgBpOAaj)

```java
formatBaseN( 1024, 16 );

```

Result: 400

### Format 125 as decimal number

[Run Example](https://try.boxlang.io/?code=eJxLyy%2FKTSxxSixO9dNQMDQy1VEwNFDQtOYCAGJHBm4%3D)

```java
formatBaseN( 125, 10 );

```

Result: 125

### Format a float

Floors float to integer then formats with radix given

[Run Example](https://try.boxlang.io/?code=eJxLyy%2FKTSxxSixO9dNQMDTQMzfVUTBS0LTmAgBpTQai)

```java
formatBaseN( 10.75, 2 );

```

Result: 1010

### Additional Examples

```java
<bx:output>
  #formatBaseN( 15, 2 )# <!--- 1111 (binary) ---> 
  #formatBaseN( 15, 16 )# <!--- f (hexadecimal) ---> 
  #formatBaseN( 15, 8 )# <!--- 17 (octal) ---> 
</bx:output>
```

```java
<bx:set max = CreateObject( "java", "java.lang.Integer" ).MAX_VALUE >
<bx:output>
  #formatBaseN( max, 16 )# <!--- 7fffffff (correct) ---> 
  #formatBaseN( max + 1, 16 )# <!--- 7fffffff (incorrect) ---> 
</bx:output>
```

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:

```
GET https://boxlang.ortusbooks.com/boxlang-language/reference/built-in-functions/math/formatbasen.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
