log10() function for complex number in C++ Last Updated : 18 Aug, 2022 Summarize Comments Improve Suggest changes Share Like Article Like Report The log10() function for complex numbers is defined in the complex header file. This function is the complex version of the log10() function. This function is used to calculate the complex common log of a complex number z i.e with base 10 and returns the common log of complex number z. Syntax: template<class T> complex<T> log10 (const complex<T>& z ); Parameter: This method takes a mandatory parameter z which represents the complex number. Return value: This function returns the common log of the complex number z. Below programs illustrate the log10() function in C++: Example 1: cpp // C++ program to demonstrate // example of log10() function. #include& lt; bits / stdc++.h & gt; using namespace std; // driver program int main() { // initializing the complex: (-1.0+0.0i) complex& lt; double& gt; complexnumber(-1.0, 0.0); // use of log10() function for complex number cout& lt; < " The log10 of& quot; < < complexnumber& lt; < " is& quot; < < log10(complexnumber) & lt; < endl; return 0; } Output:The log10 of (-1,0) is (0,1.36438) Time Complexity: O(1) Auxiliary Space: O(1) Example 2: cpp // C++ program to demonstrate // example of log10() function. #include& lt; bits / stdc++.h & gt; using namespace std; // Driver program int main() { // Initializing the complex: (-1.0 + -0.0i) complex& lt; double& gt; complexnumber(-1.0, -0.0); // use of log10() function for complex number cout& lt; < " The log10 of& quot; < < complexnumber& lt; < " is& quot; < < log10(complexnumber) & lt; < endl; return 0; } Output:The log10 of (-1,-0) is (0,-1.36438) Time Complexity: O(1) Auxiliary Space: O(1) Comment More infoAdvertise with us Next Article pow() function for complex number in C++ B bansal_rtk_ Follow Improve Article Tags : Misc C++ CPP-Library CPP-Functions CPP-complex +1 More Practice Tags : CPPMisc Similar Reads log() function for complex number in C++ The log() function for complex number is defined in the complex header file.
