int x;
x= (int) (7.0/2);
I need to know why it is essential to use (int) in the statement above?
What is it called?
How it would be without (int), is it correct?

Re: why it is essential to use (int) ?
Its because your trying to use a float... 7.0 is a float value, But stating (int) is just like parsing it to an int from a float which it currently is.
7.0 = Decimal point number = Float
7 = no Decimal Point = int
you are saying 7.0 divided by 2.. although your saying that the answer will equal the int x.
So long story short.. you cannot use a float value as an int unless u do either (int) or parse the float.
Re: why it is essential to use (int) ?
Because the literal "7.0" is implicit double value, so the result of 7.0/2 will be a double number, theno you need to put a type cast (int) to convert the result into an integer which is assigned to the variable x which is an integer.Originally Posted by websit

Wrong, float literal is a double value, implicitly.
