I can't seem to find a sincos function - does Framewave contain a single function to compute both?
We don't have it at the moment, but we can certainly provide it.
We will work on this and keep you posted
If it helps, there is a sincos function in a binary library from AMD. libmv is a part of ACML which can be found at - http://developer.amd.com/cpu/libraries/acml/Pages/default.aspx.
