r/javahelp on Reddit: How do I round an int to the nearest number?

October 2, 2017 -

Hello r/javahelp! I'm learning Java on my own and have been doing some exercises a friend gave me of his past classes when I expressed interest in coding. One of the exercises is to make a program where you convert yards into miles only using ints and a set of numbers given (Example: 60000/70000). Here's the current rendition of the code. For some reason I can't get the numbers that should round, to round (Example: 70000 should round to 40, but I still get 39). I've even tried Math.round() but it doesn't seem to work. In the code, I was hoping that adding 0.5 would bump the round up to 40, but it doesn't. It's really perplexing.

When you divide an int, it gets truncated, which is slightly different to rounding: everything after the decimal point just gets chopped off. So 39.1 becomes 39, and 39.5 becomes 39, and 39.999 becomes 39. Using Math.round should have the functionality you want, so if it's not working post some more code so we can help figure out the problem.

How do you round a number to the closest integer in java without using the "round function" or "if and else statements"? - Stack Overflow

The answer is pretty simple. Add 0.5 to the number and then cast it to an int. Like this:

int rounded = (int) (unrounded + 0.5);

This works because if the decimal part is less than 0.5, the integer part stays the same, and truncation gives the right result. If the decimal part is more that 0.5, the integer part increments, and again truncation gives what we want.
