@steffenlarsen Sorry, please rebase on top of HEAD before re-running WIndows CI, it has a fix to prevent breaking Windows build runners. Thanks |
The current implementation of the tanh function for the SYCL complex extension did not always return values precise enough, neither on device nor on host. This was caused by accumulated error from a call to cos. This commit changes the implementation of tanh to use a different way of calculating the result and tests it against std::tanh for complex numbers.
