BR-DEC-11 The sum of document-level charges may have at most two decimals

"declaredTotals": { "chargeTotalAmount": 5.01 }

  "severity": "fatal",
  "message": "The allowed maximum number of decimals for the Sum of charges on document level (BT-108) is 2, but you declared 5.005, which has 3. The rule is written against the serialised value — the schematron counts the characters after the decimal point in the XML — so the check is about what gets written, not about what the number \"really\" is. Charges are the usual home of per-unit and percentage-based figures — freight per kilo, a 1.5% handling fee — so this is the total most likely to inherit a long decimal from the arithmetic that produced it.",
  "fix": "Round declaredTotals.chargeTotalAmount to two decimals (5.01 here) using half-up rounding away from zero, for which this package exports round2(). Alternatively drop declaredTotals and let the library compute the totals, which it always rounds correctly.",
