◆ sec

eve::sec = {}
inlineconstexpr

Callable object computing the secant of the input.

Defined in Header

#include <eve/module/math.hpp>

Callable Signatures

namespace eve
{
template< eve::floating_value T >
T sec(T x) noexcept; //1
template< eve::floating_value T >
as_complex_t<T> sec(as_complex_t<T> z) noexcept; //2
}
constexpr callable_sec_ sec
Callable object computing the secant of the input.
Definition: sec.hpp:73
Definition: abi.hpp:18

Parameters

Return value

  1. Returns the elementwise secant of the input (inverse of the cosine).

    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.
  2. Returns elementwise the secant of the input i.e. \(\1/cos(z)\).

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>()), eve::pi(eve::as<float>())};
std::cout << "---- simd" << '\n'
<< "<- pf = " << pf << '\n'
<< "-> sec(pf) = " << eve::sec(pf) << '\n'
;
float xf = 3.0f;
std::cout << "---- scalar" << '\n'
<< "<- xf = " << xf << '\n'
<< "-> sec(xf) = " << eve::sec(xf) << '\n';
return 0;
}
