◆ asec

eve::asec = {}
inlineconstexpr

Callable object computing the arc secant.

Defined in Header

#include <eve/module/math.hpp>

Callable Signatures

namespace eve
{
template< eve::floating_value T >
T asec(T x) noexcept;
}
constexpr callable_asec_ asec
Callable object computing the arc secant.
Definition: asec.hpp:59
Definition: all_of.hpp:22

Parameters

x: floating real value.

Return value

Returns the elementwise arc secant of the input in the range \([0 , \pi]\).

In particular:

  • If the element is \(1\), \(+0\) is returned.
  • If the element is \(0\), \(\pi\) is returned.
  • If the element \(|x| < 1\), 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 = { 0.0f, 2.0f, -1.0f, -0.5f};
std::cout
<< "---- simd" << '\n'
<< "<- pf = " << pf << '\n'
<< "-> asec(pf) = " << eve::asec(pf) << '\n'
;
float xf = 1.0f;
float yf = eve::inf(eve::as<float>());
std::cout
<< "---- scalar" << '\n'
<< "<- xf = " << xf << '\n'
<< "-> asec(xf) = " << eve::asec(xf) << '\n'
<< "<- yf = = " << yf << '\n'
<< "-> asec(yf) = " << eve::asec(yf) << '\n';
return 0;
