radinpi

auto eve::radinpi = functor<radinpi_t>

inlineconstexpr

Header file

#include <eve/module/math.hpp>

Callable Signatures

namespace eve
{
   // Regular overload
   constexpr auto radinpi(floating_value auto x)                          noexcept; // 1
 
   // Lanes masking
   constexpr auto radinpi[conditional_expr auto c](floating_value auto x) noexcept; // 2
   constexpr auto radinpi[logical_value auto m](floating_value auto x)    noexcept; // 2
}

Parameters

• x: floating value.
• c: Conditional expression masking the operation.
• m: Logical value masking the operation.

Return value

1. Returns the radian input converted in \(\pi\) multiples.
2. The operation is performed conditionnaly.

Example

// revision 1
#include <eve/module/math.hpp>
#include <iostream> 
 
int main()
{ 
  eve::wide<float> wf([](auto i, auto c)->float{ return 2*(i-c/2);}); 
  
  std::cout << "<- wf = " << wf << "\n"; 
  
  std::cout << "-> radinpi(wf)                = " << eve::radinpi(wf) << "\n";
  std::cout << "-> radinpi[ignore_last(2)](wf)= " << eve::radinpi[eve::ignore_last(2)](wf) << "\n";
  std::cout << "-> radinpi[wf != -2.0f](wf)   = " << eve::radinpi[wf != -2.0f](wf) << "\n";
