The default options value is `- . ,`.

Numbers greater than or equal to 5 are rounded up. For example, if precision is set to `0`, `1.5` becomes `2`, and `1.4` becomes `1`.

```
{{ lang.NumFmt "," "." "-" 2 12345.6789 }} → 12.345,68
{{ lang.NumFmt "." "" "-" 6 -12345.6789 }} → -12345.678900
{{ lang.NumFmt "." "," "-" 0 -12345.6789 }} → -12,346
{{ -98765.4321 | lang.NumFmt "." "," "-" 2 }} → -98,765.43
```
