Historically, that has been true. According to this document... https://developer.nvidia.com/sites/default/files/akamai/cuda/files/NVIDIA-CUDA-Floating-Point.pdf ...NVidia's GPU cards which implement "compute capability" versions 2.0 and higher are IEEE-754 compliant, both for single- and double-precision floating point operations. The current "compute capability" version is 5.2, so there are several generations of GPU hardware out there by now which should give satisfactory floating-point results. -- https://mail.python.org/mailman/listinfo/python-list
