◆ min

eve::min = {}
inlineconstexpr

Computes the minimum of its arguments.

Defined in Header

#include <eve/module/core.hpp>

Callable Signatures

namespace eve
{
template< eve::value T, eve::value... Ts >
eve::common_value_t<T, Ts...> min(T x, Ts ... xs) noexcept;
}
Definition: value.hpp:31
constexpr callable_min_ min
Computes the minimum of its arguments.
Definition: min.hpp:84
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.
Definition: common_value.hpp:50

Parameters

Return value

The value of the minimum of the arguments is returned.

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