How cash rounding works
Results depend on the rounding rule, step size, and tie handling. Document the rule and share it to keep operations consistent.
- Round and nearest can differ based on how ties are handled.
- Set the step to match local cash practice (e.g. 0.05).
- Share what the rule applies to (subtotal/total/tax) to avoid confusion.
سؤالات متداول
How do I round to 0.05?
Choose step 0.05 and select round/nearest/ceil/floor. You can also pick a tie-handling rule for nearest.
Can I use this with tax calculation?
Yes. You can carry the same rounding rule from the tax converter (shareable settings link).
Does it support bulk input?
Yes. Paste multiple lines (one amount per line) to process in bulk.
Can I round negative amounts (refunds/discounts)?
Yes. Negative values are supported. Results depend on the tie-handling rule for nearest.
What about floating-point errors?
The calculation uses the selected step size internally and rounds display by the chosen digits. Increase display digits if needed.
