constexpr callable_cotpi_ cotpi
Callable object computing the arc cotangent from an input in multiples.
Definition: cotpi.hpp:77
Definition: all_of.hpp:22
SIMD-compatible representation of complex numbers.
Definition: complex.hpp:40
Parameters
Return value
- Returns the elementwise cotangent of the input expressed in \(\pi\) multiples. In particular:
- If the element is \(\pm0\), \(\pm\infty\) is returned.
- If the element is \(\pm\infty\), Nan is returned.
- If the element is a
Nan
, NaN
is returned.
- Returns elementwise the cotangent of the input in \(\pi\) multiples. The behavior of this function is equivalent to
eve::rec(eve::tanpi(z))
.
