Java Programming question - easy! (opinion based)

[mcoski]

I need to calculate Miles Per Gallon of a trip. Basically taking user input of miles consumed, starting and ending mileage. The program works find, but my question is more of which variable type should I use. I converted all input strings to double to give a more precise answer but then the answer given in the end is long if it doesn't divide easily. Should I stick with what I have or go for integers all the way through?

I would use double to work the problem and convert back to an integer for the answer.

Use double all the way through, round the answer to 2 or 3 decimal places before displaying it to the user.

use the google calculator

(use double all the way through, and control how you display the number)

Not that it really matters in this case, but float would be more than enough.
