The total amount of time off requested for the whole range, in the category's unit, with at most 2 decimal places. It is split evenly across the days from startDate to endDate (inclusive) that have default hours for the employee, the same days the request form prefills. Holidays and days with no default hours (usually weekends) get no amount; if no day in the range has default hours, the request is rejected. When the amount does not divide evenly, the remainder is added 0.01 at a time to the last days, so the per-day amounts sum to amount (for example, 10 over 3 days is 3.33, 3.33, 3.34). Supply dailyAmounts instead to set each day's amount. Supply exactly one of 'amount' or 'dailyAmounts'.
