There is a logarithm function in C++. It's "log" after importing math.h. You can find more info here: http://www.cplusplus.com/reference/cmath/log10/. Hope it helps you 😉


The logarithm to a base b (e.g. 10) of a number is the value which if b is raised to the power of by gives you back the original number. This is not to confused with algorithm which is a set of steps or a procedure to follow to achieve a certain result or to solve a problem.


By library "cmath" for: - ln(x) ---> log(x) - log_b=10 ---> log10(x)
