How regras de arredondamento differ
Cash arredondamento is often applied to the final payable amount, tax amounts, or displayed preços. Even with the same 0.05 passo, nearest, round up, and round down produce different resultadoados.
Store rules are easier to misread when the apply target and tie rule are omitted, so this page keeps the rule summary visible next to the resultado.
Perguntas frequentes
Can I round to 0.05?
Yes. Choose 0.05 as the passo, then select round half up, round up, round down, or nearest. In nearest mode you can also choose how ties are handled.
Can I use it together with tax calculations?
Tax calculation itself belongs in a separate tool. This page only rounds the value you enter, and it is designed to reuse the same rule definition as a tax-conversion workflow.
Can I paste multiple values at once?
Yes. The batch tab accepts multiple lines and lets you export the resultado as CSV or copy it as TSV.
Can it round negative amounts?
Yes. Returns and descontos can be rounded as negative values. Because the meaning of round up, round down, and tie handling changes with negatives, always review the resultado carefully.
Does it avoid decimal precision errors?
Yes. The calculation uses decimal-safe integer scaling internally, so passos like 0.05 are not handled with binary floating-point arithmetic.
