end

.format(amount) ⇒ Object

Indian digit grouping: 12,34,567 — not the western 1,234,567. It lives here rather than only in the view helper because the slip PDF is rendered by HOST code (config.render_pdf), where engine helpers are out of scope — which is why the PDF printed a bare "75000.0" next to the web slip's "₹75,000.00".
