..., llvmpipe has C-binding code that generates (inlines) log/exp/pow/sin/cos functions of the fly, for an arbitrary number of elements (in most cases), and uses sse/avx intrinsics as available: http://cgit.freedesktop.org/mesa/mesa/tree/src/gallium/auxiliary/gallivm/lp_bld_arit.c The precision is 20bits, which is enough for 3D. But it wouldn't be difficult to have more (or even variable) precision, by using higher degree approximating functions were appropriate. The code is in a permissible license.

Hi everyone, I was looking at loop vectorizer code and wondered if there was any current or planned effort to introduce SIMD implementations of sin/cos/exp/log intrinsics (in particular for x86-64 backend)?

I have a situation where I need to get the first class name of an element. Element.ClassNames() returns an object not an array... Object.values() will turn it into an array, but the API Docs say that the order of the resulting array is browser-dependent.. So for my use is no good... So I am using: el.className.split(" ").first(); Can any one see any problems that I might

Hey, I''m brand new to AJAX and scriptalicious, so i''m hoping for some help. inside hello.php I have this piece of code to grab and loop out users in the database: function test(){ $query = mysql_query(''SELECT * FROM `testing`''); while($i = mysql_fetch_row($query)) { echo''<div class="testie">'';
