IF higher or equal

The following syntax trigger a `TemplateSyntaxError`

```
{% if me.number >= 0 %}
// Uncaught exception 'TemplateSyntaxError' with message 'unexpected character in filters : "="
```

Also using negative value does the same problem

```
{% if me.number > -1 %}
Uncaught exception 'TemplateSyntaxError' with message 'unexpected character in filters : "-"
```
