std::normal_distribution results in wrong order windows versus linux?

Question

Anyone came access this issue? Per 1 the implementations are not required to produce same data. What about in practice - are there many differences in STL implementations am

Answer 1

Several common methods of generating normally distributed random numbers, such as the Box-Muller transform and the Marsaglia polar method, generate two random numbers at once. A distribution object using one of those methods would generate two random numbers, return one of them, and save the other one for the next time it's called.

Which one is returned and which one is stored is, of course, completely up to the library author. It looks like libstdc++ and MSVC use the same algorithm, but happen to choose differently.
