Examples

Get currency by code

const currency = getByCode('EUR');
console.log(currency);

Get currency by number

const currency = getByNumber('978');
console.log(currency);

Check if a string is a valid currency code

const isValid = isCurrencyCode('USD');
console.log(isValid); // true

Convert to major unit

const majorUnit = toMajorUnit({ value: 100_000, currency: 'USD' });
console.log(majorUnit); // 1000

Convert to minor unit

const minorUnit = toMinorUnit(1000, 'USD');
console.log(minorUnit); // 100_000

Get symbol by currency code

const symbol = getSymbolByCode('USD');
console.log(symbol); // $

Check if an object is a valid amount

const validAmount = isAmount({ value: 1000, currency: 'USD' });
console.log(validAmount); // true

Calculate exchange rate

const rate = calculateRate({ value: 1000, currency: 'USD' }, { value: 800, currency: 'EUR' });
console.log(rate); // 0.8

Apply exchange rate to amount

const convertedAmount = applyRate({ value: 100_000, currency: 'USD' }, 'EUR', 0.8);
console.log(convertedAmount); // { value: 80_000, currency: 'EUR' }
