clog10, clog10f, clog10l

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

Syntax

_Dcomplexclog10( _Dcomplexz ); _Fcomplexclog10f( _Fcomplexz ); _Lcomplexclog10l( _Lcomplexz );
_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 parameterReturn value
PositiveThe logarithm (base 10) of z
Zero- INF
NegativeNaN
NaNNaN
+ 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.
