The second if statement therefore is in fact an 'also if'. The otherwise is associated with both if statements, and the associated statements will only be executed if neither if statement is true. The second condition is also tested, found to be true, and the associated statements are executed. The first condition is tested and found to be true, and the associated statements are executed.

I never seen also if in one real calculation!
