Is noise output identical across platforms? #147

Just wondering, if I usan identical node graph with the same settings to generate noise, will the results be bit-for-bit identical across supported platforms and compilers, no matter which instruction set is chosen? Thanks.

edit: in case it wasn't clear, I'm asking specifically about the C++ version only, i.e. different architectures/compilers/instruction sets, rather than any ports to other languages.

It's not bit for bit identical, there will be some minute floating point error level differences. Although I'm working towards having an optional mode that is bit identical with some performance sacrifice
