Header file

#include <eve/module/math.hpp>

Callable Signatures

namespace eve
{
   // Regular overload
   constexpr auto coth(floating_value auto x)                          noexcept; // 1
 
   // Lanes masking
   constexpr auto coth[conditional_expr auto c](floating_value auto x) noexcept; // 2
   constexpr auto coth[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 hyperbolic cotangent of the input. In particular:
   • If the element is \(\pm0\), \(\pm\infty\) is returned.
   • If the element is \(\pm\infty\), \(\pm1\) is returned.
   • If the element is a NaN, NaN is returned.
2. The operation is performed conditionnaly.
