What is the value assigned to num

Question

What is the value assigned to num in the statement: double num = 5/2;?

Some websites say 2 some say 2.5. Help please.

Answer 1

2 in JAVA
Because 5/2 is 2.5 ,Round off 2.
For 2.5,
double x=5/2f;

Answer 2

It will be 2. This is because 5 and 2 are both integer literals, so integer division will be performed. As per the definition of integers, there won't be any floating point component (any remainder will just be dropped).

To get 2.5, at least one of them will need to be floating point literal, and the other will be implicitly converted. E.g., 5.0 or 2.0

Answer 3

You can test it on the code playground.
