The original motive for this topic was a minor improvement (in my opinion) to the source code mainly for aesthetic, rather than functional, reasons - the functional improvement is very minor.
During the discussion some minor, again mainly aesthetic, improvements to the Docu were discovered.
However the later idea of adding the SinCos function is an important functional addition. It simplifies, and makes significant speed improvements, to major subject areas, like signal processing, and to the widely used Fast Fourier Transform (FFT) algorithm.
For these reasons I hope you can support this issue.
