◆ sinpic

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
}
Specifies that a type is a Conditional Expression.
Definition: conditional.hpp:27
The concept floating_value<T> is satisfied if and only if T satisfies eve::value and the element type...
Definition: value.hpp:95
The concept logical_value<T> is satisfied if and only if T satisfies eve::value and the element type ...
Definition: value.hpp:107
constexpr auto sinpic
elementwise_callable object computing the normalized cardinal sine.
Definition: sinpic.hpp:72
EVE Main Namespace.
Definition: abi.hpp:18

Parameters

* `x`: [floating value](@ref eve::floating_value).
* `c`: [Conditional expression](@ref conditional_expr) masking the operation.
* `m`: [Logical value](@ref logical) 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.

std::cout << "-> sinpic[wf != 2.0f](wf) = " << eve::sinpic[wf != 2.0f](wf) << "\n";
