◆ cosd

eve::cosd = {}
inlineconstexpr

Callable object computing cosine from an input in degrees.

Defined in Header

#include <eve/module/math.hpp>

Callable Signatures

namespace eve
{
template< eve::floating_value T >
T cosd(T x) noexcept;
}
constexpr callable_cosd_ cosd
Callable object computing cosine from an input in degrees.
Definition: cosd.hpp:64
Definition: all_of.hpp:22

Parameters

x: floating real value.

Return value

Returns the elementwise cosine of the input expressed in degrees.

In particular:

  • If the element is \(\pm0\), \(1\) is returned.
  • If the element is \(\pm\infty\), Nan is returned.
  • If the element is a NaN, NaN is returned.

Example

#include <eve/module/math.hpp>
#include <eve/wide.hpp>
#include <iostream>
int main()
{
wide_ft pf = {1.0f, 0.0f, eve::inf(eve::as<float>()), 180.0f};
std::cout << "---- simd" << '\n'
<< "<- pf = " << pf << '\n'
<< "-> cosd(pf) = " << eve::cosd(pf) << '\n'
;
float xf = 3.0f;
std::cout << "---- scalar" << '\n'
<< "<- xf = " << xf << '\n'
<< "-> cosd(xf) = " << eve::cosd(xf) << '\n';
return 0;
}
constexpr callable_inf_ inf
Computes the infinity ieee value.
