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
• integer index

index supports negative indexes. If the type of the entry at index in src is not a float it is typecast into 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);

    {
        list my_list = ["a", 1, 2.0, <1,2,3>, <1,2,3,4>, llGetOwner()];
        integer i;
        for (i=0;i<llGetListLength(my_list); ++i)
        {
            llOwnerSay("string=" + llList2String(my_list,i)
                        + "\n   integer=" + (string)llList2Integer(my_list,i)
                        + "\n   float=" + (string)llList2Float(my_list,i)

                        + "\n   rot=" + (string)llList2Rot(my_list,i)
                        + "\n   key=" + (string)llList2Key(my_list,i) );
        }
