Log base 2 function
Note: Most Sirius $functions have been deprecated in favor of Object Oriented methods. The OO equivalent for the $Log2 function is the Log2 function.
The $Log2 function (or its alias, $Log_2) returns the base-2 logarithm of the number x.
Syntax
%num = $Log2(x)
%num = $Log_2(x)
Usage notes
- If x is not greater than 0, an error message is printed and the request is cancelled.
