zend_ast_export() - float number is not preserved

### Description

The following code:

```php
<?php

assert(!is_float(0.0));
```

Resulted in this output:
```
Uncaught AssertionError: assert(!is_float(0))
```

But I expected this output instead:
```
Uncaught AssertionError: assert(!is_float(0.0))
```

The dumped AST must preserve the original meaning.
