General 2nd order filter lets you choose between single or double precision, but the 2nd order lookup and 2nd order lookup/slew don't. Are they single or double precision?
General (2nd Order/Lookup) is double precision.
General 2nd Order w var Param/Lookup/Slew is also double precision.
I saw that you already updated the Wiki page to reflect the fact that these filters are double precision. Thank you for taking the initiative to do that. I have approved your update.
