Retrieves the arccosine of a complex number, with branch cuts outside the interval [-1, +1] along the real axis.
_Dcomplex cacos( _Dcomplex z );
_Fcomplex cacosf( _Fcomplex z );
_Lcomplex cacosl( _Lcomplex z );
_Fcomplex cacos( _Fcomplex z ); // C++ only
_Lcomplex cacos( _Lcomplex z ); // C++ only
z
A complex number that represents an angle, in radians.
The arc cosine of z
, in radians. The result is unbounded along the imaginary axis, and bounded in the interval [0, π] along the real axis. A domain error will occur if z
is outside the interval [-1, +1].
Because C++ allows overloading, you can call overloads of cacos
that take and return _Fcomplex
and _Lcomplex
values. In a C program, cacos
always takes and returns a _Dcomplex
value.
