Callable Signatures

namespace eve
{
// Regular overload
constexpr auto acoth(floating_value auto x) noexcept; // 1

constexpr auto acoth[logical_value auto m](floating_value auto x) noexcept; // 2

Specifies that a type is a Conditional Expression.

Definition value.hpp:132
constexpr auto acoth
elementwise_callable object computing the inverse hyperbolic cotangent.
Definition acoth.hpp:77
EVE Main Namespace.
Definition abi.hpp:18

Parameters

Return value

  1. Returns the elementwise inverse hyperbolic cotangent of the input in the range \([-\frac\pi2, \frac\pi2]\). In particular:
    • If the element is \(\pm1\), \(\pm0\) is returned.
    • If the element is \(\pm\infty\), \(\pm1\) is returned.
    • If the element is less than one or a NaN, NaN is returned.
  2. The operation is performed conditionnaly.
