I am sorry, it seems to be unreadable bacause of my very bad english. I try to correct it little bit.
Hi Friends :-) Is there a possibility to have sin, cos anD acos, functions in sqlite? How to write it in? I have read (Mike Owens article at LinuxJournal), that it is possible to write new function to expand standard set of functions as avg(), min(), sum() etc. I will have table with sequence of coordinates (two dimensional space) and corresponding radiuses, so sequence of circles. And i need to use a sqlite query to detect if a actual coordinates (after their measurement) match some of the circle's square or not. And which circle, if match. And this must be for low CPU consumption optimised, so i am not sure, if separate sin table queries will be enough as fast as i need at needed precission. The whole algorithm is proven on mssql by my colegue, but he is using the native math functions.
