how can a logarithm be solved on the iphone. I tried using different methods with the log2f and all those however I wasnt sure exactly how to make a log lets say log (base4) 5 = x and x would be given as the answer
+1
A:
log_a(x)=log_b(x) / log_b(a) where a is the base you want and b is any other base. In particular log base 4 of 5 is log2f(5)/log2f(4)
