//   the largest.
//
// Parameters (in ascending coin value):
//   oneCent    - number of 1‑cent coins
//   twoCent    - number of 2‑cent coins
//   fiveCent   - number of 5‑cent coins
//   tenCent    - number of 10‑cent coins
//   twentyCent - number of 20‑cent coins
//   fiftyCent  - number of 50‑cent coins
//   oneEuro    - number of 1‑euro coins
//   twoEuro    - number of 2‑euro coins
//
// Returns:
//   Total value in euros as a double.
