clog10, clog10f, clog10l

Retrieves the logarithm (base 10) of a complex number.

Syntax

_Dcomplex clog10( _Dcomplex z );
_Fcomplex clog10f( _Fcomplex z );
_Lcomplex clog10l( _Lcomplex z );

_Fcomplex clog10( _Fcomplex z );  // C++ only
_Lcomplex clog10( _Lcomplex z );  // C++ only

Parameters

z
The base of the logarithm.

Return value

The possible return values are:

z parameter	Return value
Positive	The logarithm (base 10) of z
Zero	- INF
Negative	NaN
NaN	NaN
+ INF	+ INF

Remarks

Because C++ allows overloading, you can call overloads of clog10 that take and return _Fcomplex and _Lcomplex values. In a C program, clog10 always takes and returns a _Dcomplex value.

Requirements

Routine	C header	C++ header
clog10, clog10f, clog10l	<complex.h>	<ccomplex>
