doubles & rounding
I'm working on an ASCII version of battleship, and as part of the project, the hit/miss stats have to be printed out at the end. Because this is for a computer science course, my output has to be identical to the required output.
My program prints this: Hit ratio: 66.66666666666667% When it should be printing: Hit ratio: 66.66666666666666% and.. My Program: Hit ratio: 33.333333333333336% Required output: Hit ratio: 33.33333333333333% I'm assuming that this is happening because of the way doubles behave, but I have no idea how I would fix that. Here's the code that computes the ratio: double ratio = 100.0 * numHit / numFired; Where numHit is a double representing the number of missiles that hit and numFired is a double representing the number of missiles fired 
Re: doubles & rounding
try using long instead of double.

Re: doubles & rounding
Long won't get you any decimal places. There are two issues. One is that the accuracy of the operation is constrained by the particular floatingpoint implementation. The other is a question of adjusting and formatting the results that you get.
