Compute the base-e exponential of a complex number.

Syntax

_Dcomplex cexp(   
   _Dcomplex z   
);  
_Fcomplex cexp(   
   _Fcomplex z   
);  // C++ only  
_Lcomplex cexp(   
   _Lcomplex z   
);  // C++ only  
_Fcomplex cexpf(   
  _Fcomplex z   
);  
_Lcomplex cexpl(   
   _Lcomplex z   
);

Parameters

z
A complex number that represents the exponent.

Return Value

The value of e raised to the power of z.

Remarks

Because C++ allows overloading, you can call overloads of cexp that take and return _Fcomplex and _Lcomplex values. In a C program, cexp always takes and returns a _Dcomplex value.

Requirements

Routine	C header	C++ header
`cexp`, `cexpf`, `cexpl`	<complex.h>	<complex.h>
