Summary
Function: float llList2Float( list src, integer index );187 | Function ID |
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.
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.
- When used to typecast from a string it can only handle floats in simple notation. It will not handle hex formats or scientific notation.
- A true typecast will handle both properly: (float)llList2String(src, index);
