◆ negminabs

eve::negminabs = {}
inlineconstexpr

Computes the negated value of the element of the minimal absolute value.

Defined in Header

#include <eve/module/core.hpp>

Definition: value.hpp:31
constexpr callable_negminabs_ negminabs
Computes the negated value of the element of the minimal absolute value.
Definition: negminabs.hpp:71
Definition: abi.hpp:18
typename eve::detail::common_value_impl< void, Ts... >::type common_value_t
Computes the SIMD-compatible common type between all Ts.

Parameters

Return value

The negated negated value of the element of the minimal absolute value is returned.

Note
If any element of the inputs is a NaN, the corresponding output element is system-dependent.
