but when i do 1000000000 * 3.0 = 3000000000
But this is didnt happend when i multiply with 1 or 2. Can some one explain?
In the first example, it is doing integer multiplication but the result is greater the limit of an "int" datatype (which is 2 147 483 647), and so the result is "overflowing" or "wrapping" and gives you a negative number. To fix this, typecast it as a "long" (which has a limit of 9 223 372 036 854 775 807).
In the second example, it is doing floating-point multiplication and the results are within the capabilities of that datatype.
