Question

what is the value of (double)(5/2)? a 2.0 b 3 c 3.0 d 2 e 2.5

Explanation:

Step1: Analyze the operation inside the cast

First, we consider the division \(5/2\). In integer division (if we were dealing with integers), \(5\div2 = 2\) with a remainder, but here we are casting to double which is a floating - point type. When we perform \(5\div2\) in a floating - point context (because we are casting the result to double), we calculate the exact value of the fraction. The fraction \(\frac{5}{2}\) is equal to \(2.5\).

Step2: Consider the type casting

The (double) cast is used to convert the result of the division to a double - precision floating - point number. Since \(\frac{5}{2}=2.5\), when we cast it to double, the value remains \(2.5\) (because \(2.5\) is a valid double - precision floating - point number).

Answer:

E. 2.5
