Computes the complex hyperbolic tangent of a complex number.
_Dcomplex ctanh( _Dcomplex z ); _Fcomplex ctanh( _Fcomplex z ); // C++ only _Lcomplex ctanh( _Lcomplex z ); // C++ only _Fcomplex ctanhf( _Fcomplex z ); _Lcomplex ctanhl( _Lcomplex z );
Parameters
z
A complex number that represents an angle, in radians.
The complex hyperbolic 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 ctanh that take and return _Fcomplex and _Lcomplex values. In a C program, ctanh always takes and returns a _Dcomplex value.
