Log base 2 function

Note: Many $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.
