Retrieves the base 10 logarithm of a complex number.
_Dcomplex clog10( _Dcomplex z ); _Fcomplex clog10( _Fcomplex z ); // C++ only _Lcomplex clog10( _Lcomplex z ); // C++ only _Fcomplex clog10f( _Fcomplex z ); _Lcomplex clog10l( _Lcomplex z );
Parameters
z
The base of the logarithm.
The possible return values are:
| z parameter | Return value |
|---|---|
| Positive | The base 10 logarithm of z |
| Zero | - ∞ |
| Negative | NaN |
| NaN | NaN |
| + ∞ | + ∞ |
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.
| Routine | C header | C++ header |
