Log is included by default in each file as part of the Math library.
The Log() function returns the logarithm of a number. By default, it uses base 10, but the base can be given as the second input.
Log() inputs must be unitless, as units aren't compatible with taking logarithms.
Log() is compatible with complex numbers.
Log(100) = 2
Log(32, 2) = 5
Log(10i) = 1 + 0.682i
