namespace eve
{
   // Regular overload
   constexpr auto sinpicospi(floating_value auto x)                          noexcept; // 1
 
   // Lanes masking
   constexpr auto sinpicospi[conditional_expr auto c](floating_value auto x) noexcept; // 2
   constexpr auto sinpicospi[logical_value auto m](floating_value auto x)    noexcept; // 2
 
   // Semantic options
   constexpr auto sinpicospi[quarter_circle](floating_value auto x)          noexcept; // 3
}

Parameters

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

Return value 1 .The computation returns a tuple-like whose elements are sinpi(x) and cospi(x)

1. The operation is performed conditionnaly.
2. Assumes that the inputs elements belong to \([-1/4,\1/4]\) and return NaN outside.
