| AMREX_GPU_HOST_DEVICE AMREX_FORCE_INLINE std::uint32_t | amrex::Morton::makeSpace (std::uint32_t x) noexcept |
| | This makes space in the input 32-bit integer by splitting the bits so they can be interleaved. More...

| AMREX_GPU_HOST_DEVICE AMREX_FORCE_INLINE std::uint32_t | amrex::Morton::toUInt10 (amrex::Real x, amrex::Real xmin, amrex::Real xmax) noexcept |
| | Convert a Real to a uint32, keeping only 10 significant bits. This puts the first 10 bits of x into retval with the 22 highest bits set to 0. It is assumed that xmin <= x < xmax. More...

| AMREX_GPU_HOST_DEVICE AMREX_FORCE_INLINE std::uint32_t | amrex::Morton::toUInt16 (amrex::Real x, amrex::Real xmin, amrex::Real xmax) noexcept |
| | Convert a Real to a uint32, keeping only 16 significant bits. This puts the first 16 bits of x into retval with the 16 highest bits set to 0. It is assumed that xmin <= x < xmax. More...
