Summary
Function: float llList2Float( list src, integer index );| 0.0 | Forced Delay |
| 10.0 | Energy |
Returns a float that is at index in src.
| • list | src | – | List containing the element of interest. | |
| • integer | index | – | Index of the element of interest. |
index supports negative indexes.
If index describes a location not in src then zero is returned.
If the type of the element at index in src is not a float it is typecast to a float. If it cannot be typecast zero is returned.
 |
Important: Please read this intro of how to iterate over a list in LSL. |
Specification
| Index | Positive | Negative |
|---|---|---|
| First | 0
|
-length
|
| Last | length - 1
|
-1
|
Indexes
- Positive indexes count from the beginning, the first item being indexed as
0, the last as(length - 1).
- Negative indexes count from the far end, the first item being indexed as
-length, the last as-1.
Caveats
- If index is out of bounds the script continues to execute without an error message.
- A string of hexadecimal notation (e.g. "0x12A") or scientific notation (e.g. "6.2e+1") will be parsed as float and contain the correct value[1].
