ctan, ctanf, ctanl

Retrieves the tangent of a complex number.

Syntax

_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.

Return Value

The tangent of z.

Input SEH Exception _matherr Exception
± ∞, QNAN, IND none _DOMAIN
± ∞ (tan, tanf) INVALID _DOMAIN

Remarks

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.

Requirements

Routine C header C++ header
ctan, ctanf, ctanl <complex.h> <ccomplex>
