I need to round a double to the nearest .5. I *do not* want to end up with a number ending in .0.

I've searched around for a bit, but it seems like everyone wants to round to the nearest *multiple* of .5 rather than just the nearest half but not whole. I tried dividing by .5, rounding that, and multiplying by .5, but this still rounds to multiples of .5. Adding or subtracting .5 after this will not always round the number where it should go (you might add when you should have subtracted).

Any help would be greatly appreciated.

## Best Solution

I think that

`Math.round(num * 2) / 2.0f`

should solve the rounding to the nearest half problem:
