| 10 | Floats are truncated to integer values, strings with leadings |
| 11 | digits are converted to integers up to the first non-digit. |
| 12 | lfun-closures are converted into their function index (not adjusted |
| 13 | for inheritance), variable closure are converted into their variable |
| 14 | index. |
| 15 | Integers are just returned. |

| Zesstra | 715ec20 | 2025-07-09 22:18:31 +0200 | [diff] [blame^] | 17 | Regarding floats, it is important to keep rounding effects |
| 18 | in mind: to_int(3.1*10.0) does not return 31, but instead 30, |
| 19 | because internally the result of the multiplication is 30.999999. |

| 24 | The cast notation only works if the precise type of <value> |
| 25 | is known at compile-time. This will not be fixed - use the |
| 26 | function form instead. |
