For example: Basically you give the Math.Round method three parameters.. round integer of a double value is the positive distance between this floating-point value and the double value next larger in magnitude. The integer math solution that Ian provided is nice, but suffers from an integer overflow bug. Here is the Gantt chart: Step 1: At time 0, process P1 enters the ready queue and starts its execution for the defined time slot 3. You often need to pretty print float and double values up-to 2 to 4 decimal places in console, GUI or JSP pages.Thankfully Java provides lots of convenient methods to format a floating point number up to certain decimal places. Assuming the variables are all int, the solution could be rewritten to use long math and avoid the bug: int pageCount = (-1L + records + recordsPerPage) / recordsPerPage; If records is a long, the bug remains. Math.hypot() For example: Basically you give the Math.Round method three parameters.. coalesce: Returns the first not null value from a set of inputs. If the argument is NaN or negative, then the result is NaN. In your case, 0.7 is a double value (floating point treated as double by default unless mentioned as float - 0.7f). Both double and long are 64-bit wide and they are read in two parts, first 32-bit first time and next 32-bit second time, which is non-atomic but volatile double and long read is atomic in Java. The Double class wraps a value of the primitive type double in an object.
