What's this, an admin for apes?

export const currencyFormat = (
  value: number,
  currency: string,
  locale: string = "sv-SE",
  maximumFractionDigits: number = 2,
) => {
  const formatter = new Intl.NumberFormat(locale, {
    style: "currency",
    currency: currency,
    currencyDisplay: "narrowSymbol",
    minimumFractionDigits: 0,
    maximumFractionDigits,
  });

  return formatter.format(value);
};
