Function: float llList2Float( list src, integer index );

Returns a float that is at index in src.

• list	src
• integer	index

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.

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);

Signature
function float llList2Float( list src, integer index );
