The QRandomGenerator64 class allows one to obtain 64-bit random values from a high-quality, seed-less Random Number Generator.
QRandomGenerator64 is a simple adaptor class around QRandomGenerator, making the QRandomGenerator::generate64() function the default for operator()(), instead of the function that returns 32-bit quantities. This class is intended to be used in conjunction with Standard Library algorithms that need 64-bit quantities instead of 32-bit ones.
In all other aspects, the class is the same. Please refer to QRandomGenerator's documentation for more information.
