The Romanian Leu (RON) is the official currency of Romania, identified by the ISO 4217 code "RON" and numeric code 946. Its symbol is lei, and amounts are typically formatted with 2 decimal places (e.g., 1.234,56 lei).
In software development, currency codes are essential for e-commerce, financial applications, and internationalization. The JavaScript Intl.NumberFormat API supports formatting amounts in RON with locale-aware separators and symbols. Payment processors like Stripe and PayPal require ISO 4217 currency codes when processing transactions.
When building multi-currency applications, store amounts in the smallest unit (e.g., cents for RON) to avoid floating-point precision errors. Use the decimal places value (2) to correctly convert between major and minor units. APIs like exchangeratesapi.io and Open Exchange Rates provide real-time conversion rates for RON.
