- Ignoring method differences for negatives.
❓ 常见问题解答
常见问题解答
Which digit controls nearest whole-number rounding?
The tenths digit decides whether the ones place stays or changes.
Does 0.5 always round up?
It rounds up in Half Up, but other methods may handle ties differently.
Can I change the method on this page?
Yes. Method is editable while the target stays fixed to whole number.
Where do I round to decimal places?
Use the decimal-places hub or dedicated tenth and hundredth pages.
