Description
For the CUDA function: __half2float(x),
Are the two functions below equivalent in a SYCL program ? If 1 is not "equal" to 2, are there simple functions for conversion between half and float ? The
1 sycl::vec<sycl::half, 1>(x).convert<float, sycl::rounding_mode::automatic>()[0]
2 float(x)
