acscpi

kyosu::acscpi = eve::functor<acscpi_t>

inlineconstexpr

Computes the arc cosecant of the argume!nt in \(\pi\) multiples.

Header file

#include <kyosu/functions.hpp>

Callable Signatures

namespace kyosu
{
   template<eve::floating_ordered_value T>     constexpr auto acscpi(T z) noexcept;  //1
   template<kyosu::concepts::cayley_dickson T> constexpr auto acscpi(T z) noexcept;  //2
}

Parameters

• z: Value to process.

Return value

1. a real input z is treated as if complex(z) was entered.
2. Returns radinpi(acsc(z))

Example

#include <eve/wide.hpp>
#include <iostream>
 
int main()

  wide_ft ref2 = { 0.0, 1.0, 2.0, 3.0};
  auto zc = kyosu::complex_t<wide_ft>(ref1, imf1);
