cexp, cexpf, cexpl

Compute the base-e exponential of a complex number.

Syntax

_Dcomplex cexp( _Dcomplex z );
_Fcomplex cexpf( _Fcomplex z );
_Lcomplex cexpl( _Lcomplex z );

_Fcomplex cexp( _Fcomplex z );  // C++ only
_Lcomplex cexp( _Lcomplex z );  // C++ only

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>
