llList2Float

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.

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].
