Retrieves the arccosine of a complex number, with branch cuts outside the interval [−1, +1] along the real axis.
_Dcomplex cacos( _Dcomplex z ); _Fcomplex cacos( _Fcomplex z ); // C++ only _Lcomplex cacos( _Lcomplex z ); // C++ only _Fcomplex cacosf( _Fcomplex z ); _Lcomplex cacosl( _Lcomplex z );
Parameters
z
A complex number that represents an angle, in radians.
The arccosine of z, in radians. The result is unbounded along the imaginary axis, and in the 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.
