rockbox/lib/fixedpoint/fixedpoint.c, branch duke3d My Rockbox tree Undo hacks to meant to get around string formatting limitations 2017-11-21T10:01:14+00:00 Michael Sevakis jethead71@rockbox.org 2017-09-18T10:00:05+00:00 aced667f48c29a160aa4e5c0a8df037092b28189 The new vuprintf makes unnecessary workarounds due to formatting limitations. I checked grep output for whatever appeared to fit but it's possible I missed some instances because they weren't so obvious. Also, this means sound settings can dynamically work with any number of decimals rather than the current assumption of one or two. Add an ipow() function to help and take advantage of dynamic field width and precision. Consolidate string formatting of sound settings. Change-Id: I46caf534859dfd1916cd440cd25e5206b192fcd8

Replace fp_sqrt function with one that only uses shift, or and sub. 2017-10-02T00:29:38+00:00 Michael Sevakis jethead71@rockbox.org 2017-10-01T02:48:41+00:00 b2a373eb642077fbf5f1bdbe74d1e82cc534f5f2 Simply extends the current isqrt() to be able to do fractional bits and improves the initial estimate using clz(). iqrt() itself is no more and is equivalent to fp_sqrt(x, 0). The original also had a small bug where the guess comparision should have been >=, not >. Uses no large integer math or division and is very accurate (simply returns a truncated fraction).
