    here is an example of log10 in cmath:

    #include <iostream>
    #include <cmath>
    int main() {
    	int x = 8;
    	double y = 0;
    	y = log10(x);
    	std::cout << y << std::endl;
    	return 0;
    if you remove the 10 for log10, it will be log, and that represents natural log, while log10 represents the common log.
