#include <cmath>
Include dependency graph for scalar_util.h: This graph shows which files directly or indirectly include this file:Scalar utility functions mimicking GROMACS SIMD utility functions.
These versions make it possible to write functions that are templated with either a SIMD or scalar type. While some of these functions might not appear SIMD-specific, we have placed them here because the only reason to use these instead of generic function is in templated combined SIMD/non-SIMD code.
