* Change almost all other uses of qrand() to QRandomGeneratorThiago Macieira2017-11-081-1/+1
| | | | | | | | | | | | | | | | | | | The vast majority is actually switched to QRandomGenerator::bounded(), which gives a mostly uniform distribution over the [0, bound) range. There are very few floating point cases left, as many of those that did use floating point did not need to, after all. (I did leave some that were too ugly for me to understand) This commit also found a couple of calls to rand() instead of qrand(). This commit does not include changes to SSL code that continues to use qrand() (job for someone else): src/network/ssl/qsslkey_qt.cpp src/network/ssl/qsslsocket_mac.cpp tests/auto/network/ssl/qsslsocket/tst_qsslsocket.cpp Change-Id: Icd0e0d4b27cb4e5eb892fffd14b5285d43f4afbf Reviewed-by: Lars Knoll <lars.knoll@qt.io>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Especially in examples, where we should show off our convenience functions, prefer calling these functions over doing arithmetic with M_PI (or approximations thereto) and 180 (give or take simple factors). This incidentally documents what's going on, just by the name of the function used (and reveals at least one place where variables were misnamed; the return from atan is in radians, *not* degrees).

* | Be (somewhat more) consistent about the value of piEdward Welbourne2017-06-202-12/+1
|/ | | | | | | | | | | | | | | | | | | | 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.
