Retrieves the tangent of a complex number.
_Dcomplex ctan( _Dcomplex z ); _Fcomplex ctan( _Fcomplex z ); // C++ only _Lcomplex ctan( _Lcomplex z ); // C++ only _Fcomplex ctanf( _Fcomplex z ); _Lcomplex ctanl( _Lcomplex z );
Parameters
z
A complex number that represents the angle, in radians.
The tangent of z.
| Input | SEH Exception | _matherr Exception |
|---|---|---|
| ± ∞, QNAN, IND | none | _DOMAIN |
± ∞ (tan, tanf) | INVALID | _DOMAIN |
Because C++ allows overloading, you can call overloads of ctan that take and return _Fcomplex and _Lcomplex values. In a C program, ctan always takes and returns a _Dcomplex value.
