Log function
Note: Most Sirius $functions have been deprecated in favor of Object Oriented methods. The OO equivalent for the $Log function is the LogE function.
The $Log function (or its alias, $Log_e) returns the natural logarithm (the logarithm base e) of the number x.
Syntax
%num = $Log(x)
%num = $Log_e(x)
If x is not greater than 0, an error message is printed and the request is cancelled.
