| -------- | ----- | -------- | ----------------- | ------- |
| `value`  | `any` | `true`   | The value to test |         |

## Examples

### Checks if toBase64() function returns binary data

toBase64() returns base64 encoded data which is not binary

[Run Example](https://try.boxlang.io/?code=eJzLLHbKzEssqtRQKMl3SixONTPRUDBU0FTQtOYCAH7oB6I%3D)

```java
isBinary( toBase64( 1 ) );

```

Result: false

### Checks if toBinary() function returns binary data

toBinary() expects base64 encoded data and returns binary data

[Run Example](https://try.boxlang.io/?code=eJzLLHbKzEssqtRQKMlHYiUWp5qZaCgYKmiCoDUXAAs6C3s%3D)

```java
isBinary( toBinary( toBase64( 1 ) ) );

```

Result: true

writeDump( label="Numeric value", var=isBinary( 1010 ) );
writeDump( label="String value", var=isBinary( "binary" ) );
writeDump( label="Array value", var=isBinary( arrayNew( 1 ) ) );
writeDump( label="Binary value", var=isBinary( ToBinary( toBase64( "I am a string." ) ) ) );
