◆ acotd

eve::acotd = {}
inlineconstexpr

Callable object computing acotd.

Required header: #include <eve/function/acotd.hpp>

Members Functions

Member Effect
operator() the computation of acotd

auto operator()(floating_value auto x) const noexcept;
Definition: value.hpp:83

Parameters

x: floating real value.

Return value

Returns the elementwise arc cotangent of the input in the range \(]-90, 90]\).

In particular:

  • If the element is \(\pm0\), \(\pm90\) is returned.
  • If the element is \(\pm\infty\), \(\pm0\) is returned.
  • If the element is a Nan, NaN is returned.
