Why rounding rules matter
Retailers and cash-based currencies often round to the nearest 0.05 or 0.10 to avoid small coin usage. Different jurisdictions have different legal rounding requirements. Rounding can slightly increase or decrease final price — knowing how the math works helps you choose friendly pricing and avoid surprises at checkout.
Common use-cases
- Rounding cash totals to avoid issuing small coins (e.g., 0.05 in some countries).
- Psychological pricing: setting list prices that round to attractive increments after tax.
- Batch price updates when migrating a catalog to new currency or rounding policy.
Notes
This helper applies simple arithmetic rounding — for large-scale financial systems consider banker's rounding or currency-specific legal rules. For tax-inclusive pricing, compute tax then round the final price according to your jurisdiction's rules.
