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>
