I can't seem to be able to use exp() and sqrt() in CUDA.

I get:

NVCC    libavfilter/try_cuda.ptx
clang-11: warning: Unknown CUDA version. cuda.h: CUDA_VERSION=11030.
Assuming the latest supported version 10.1 [-Wunknown-cuda-version]
libavfilter/try_cuda.cu:39:19: error: use of undeclared identifier 'exp'
       float g = exp(f);

Regards,
Dylan
