How it works
We divide the number of days by the chosen days per week to get decimal weeks:
weeks = days ÷ days_per_week
For the mixed format, the whole weeks are floor(days ÷ days_per_week), and remaining days are days mod days_per_week. Rounding mode and decimal places adjust the decimal display only.
