If the argument is positive infinity then the result is positive infinity. Log log2 and log10 return. It is called a common logarithm.
Log to the base e Eulers number which is about 271828 of the parameter value numeric expression passed to it.
If 2 arguments are passed it computes the logarithm of desired base of argument a numerically value of logalogBase. For example 2 3 8. Because log is a static method of Math you always use it as Mathlog rather than as a method of a Math object you created Math is not a constructor. This function is used to compute the natural logarithm Base e of a.
