Log
Definition: Returns the natural logarithm of a number.
Most people probably have the natural logarithms for all known numbers committed to memory. If you don't, and you need to know the log for a particular number, then use the System.Mathclass and the Logmethod. This command returns the log of 100 and assigns the value to the variable $a:
$a = [math]: :log(100)
When you run this command and then echo back the value of $ a youshould get the following:
