* Port from qAsConst() to std::as_const()Marc Mutz2022-10-111-5/+5
| | | | | | | | | | | | | | | | We've been requiring C++17 since Qt 6.0, and our qAsConst use finally starts to bother us (QTBUG-99313), so time to port away from it now. Since qAsConst has exactly the same semantics as std::as_const (down to rvalue treatment, constexpr'ness and noexcept'ness), there's really nothing more to it than a global search-and-replace, with manual unstaging of the actual definition and documentation in dist/, src/corelib/doc/ and src/corelib/global/.

* Be (somewhat more) consistent about the value of piEdward Welbourne2017-06-201-7/+3
| | | | | | | | | | | | | | | | | | | | Use M_PI (and friends), where possible, in favor of hand-coded approximations of various (in)accuracies. Where that's not available (e.g. fragment shaders), use the same value that qmath.h uses for M_PI, for consistency. Replaced math.h with qmath.h in places that defined a fall-back in case math.h omits it (it's not in the C++ standard, although M_PI is in POSIX); or removed this entirely where it wasn't used. Reworked some code to reduce the amount of arithmetic needed, in the process; e.g. pulling common factors out of loops. Revised an example's doc to not waste time talking about using a six-sig-fig value for pi (which we no longer do) - it really wasn't relevant, or anything to be proud of; nor did the doc mention its later use.

* Use C++ <cmath> instead of <math.h>Allan Sandfeld Jensen2015-02-161-3/+3
| | | | | | | | | | | | | | Including math.h can pollute the default namespace, and break some compilers if cmath versions of the method are declared as using. Switching to C++ math functions also greatly simplifies handling of float qreal as C++ automatically chooses the right method. [ChangeLog][QtCore][QtMath] qmath.h no longer includes math.h, so any sources depending on that indirect inclusion may fail to build.

| | | | | | | | | | | | | | | | | | Qt copyrights are now in The Qt Company, so we could update the source code headers accordingly. In the same go we should also fix the links to point to qt.io. Outdated header.LGPL removed (use header.LGPL21 instead) Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing combination. New header.LGPL-COMM taken in the use file which were using old header.LGPL3 (src/plugins/platforms/android/extract.cpp) Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license combination Change-Id: I6f49b819a8a20cc4f88b794a8f6726d975e8ffbe Reviewed-by: Matti Paaso <matti.paaso@theqtcompany.com>
