eve::maximum = {}

inlineconstexpr

Computes the maximal value of an simd vector.

Defined in Header

#include <eve/module/core.hpp>

Callable Signatures

namespace eve
{
   template< eve::value T >
   eve::element_type_t<T> maximum(T x) noexcept;
}

Parameter

• x : argument.

Return value

The scalar maximal value.

Example

#include <eve/module/core.hpp>
#include <eve/wide.hpp>
#include <iostream>
 
using wide_ft = eve::wide<float, eve::fixed<4>>;
using wide_it = eve::wide<std::int16_t, eve::fixed<4>>;
 
int main()
{
  wide_ft pf = {-1.0f, 2.0f, -3.0f, -68.0f};
  wide_it pi = {-1, 2, -3268, 3};
 
  std::cout << "---- simd" << '\n'
            << "<- pf           = " << pf << '\n'
            << "-> maximum(pf)  = " << eve::maximum(pf) << '\n'
            << "<- pi           = " << pi << '\n'
            << "-> maximum(pi)  = " << eve::maximum(pi) << '\n';
 
  return 0;
}

Semantic Modifiers

• Masked Call

  The call eve::maximum[mask](x) provides a masked version of maximum which is equivalent to : `maximum(if_else(mask, x, valmin(as(x)))).
