### 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>
```
