Math.round and Math.ceil not working

Question

I'm trying to round the users input but I can seem to get my double to round to an int. Basically, when I enter 4.4999 it wont round up to 5.

Any ideas?

Answer 1

Math.ceil() returns the ceiled value. It can't change the value of the variable it takes as argument, because Java passes arguments by value. So you need to do

hours = Math.ceil(hours);
