A Hungarian invoice that was right, flagged as wrong

einvoice-preflight's arithmetic check compared the stated VAT total to the computed tax rounded to cents. Hungarian VAT is stated in whole forints, so a correct HUF invoice was reported as INV-018. The check now also accepts a HUF tax total that is a whole number equal to the computed tax rounded half up to the unit. Other currencies are unchanged, and a HUF total that is off by a forint still fails. Two tests pin both directions. Still open: the rules on real ERP exports rather than the CEN examples.
