A week and a half or so back, I loosened the test bounds for these functions to accommodate Fermi. (perhaps CUDA 3.1 in general) I wouldn't make too much of this. Yes, precision has somewhat regressed. But a) not catastrophically, and probably for a handsome speed gain, and b) the purpose of these tests is to make sure that something reasonable (i.e. not garbage) is returned. (Just to clarify: These precision issues are in Nvidia's special functions, and have nothing to do with GPUArray itself, which just uses them.) Andreas
