auto eve::sinpic = functor<sinpic_t>

inlineconstexpr

Header file

#include <eve/module/math.hpp>

Callable Signatures

namespace eve
{
   // Regular overload
   constexpr auto sinpic(floating_value auto x)                          noexcept; // 1
 
   // Lanes masking
   constexpr auto sinpic[conditional_expr auto c](floating_value auto x) noexcept; // 2
   constexpr auto sinpic[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 elementwise sine of the input times \(\pi\) divided by the input times \(\pi\). In particular:
   • If the element is \(\pm0\), \(1\) is returned.
   • If the element is \(\pm\infty\), 0 is returned.
   • If the element is a Nan, NaN is returned.
2. The operation is performed conditionnaly.
