Description
Enables you to find the minimum value that appears in a set of values.
Overloads
  • Minimum (fld)
  • Minimum (fld, condFld)
  • Minimum (fld, condFld, cond)
  • Minimum (x)
  • Returns
    Fractional Number
    Action
    Enables you to find the minimum value that appears in a set of values. For example:
  • If a sales report includes a field that shows the amount of each order, you can find the lowest order amount of all the orders that appear on the report (a grand total minimum amount).
  • If you break orders into groups (for example, orders grouped by the state that they come from), you can find the lowest order amount per group (in this case, per state).
  • If you break orders into date or Boolean groups (for example, orders grouped by the month in which they were placed), you can find the lowest order amount per group based on a specific change in the date or Boolean field (in this case, per month).
  • If you specify a set of individual values, you can find the lowest value in the set. For information on finding this kind of minimum, see Array summary functions.
  • Examples
    Minimum({file.QTY})
    Returns the lowest value in the QTY field.
    Minimum({orders.AMOUNT}, {orders.CUSTOMER ID})
    Identifies the smallest order in each group of orders in the Amount field (the smallest order for each customer). The orders are separated into groups whenever the value in the Customer ID field changes.
    Minimum({orders.AMOUNT}, {orders.ORDER DATE}, "monthly")
    Identifies the smallest order in each group of orders in the Amount field (the smallest order for each month). The orders are separated into groups whenever the value in the Date field changes to a new month.
    Minimum also allows you to set a ceiling on a calculation. For example: Minimum([{file.COMMISSION}, 2500]) returns the commission accrued up to a cap or ceiling of 2500. Once accrued commission passes the $2500 mark, this expression returns 2500. Thus:
    Minimum([{file.COMMISSION}, 2500])
    Returns 1575 where commission = 1575.
    Using this function in a formula forces the formula to be evaluated at print time. For more information on evaluation time considerations, see Evaluation Time.
    When using this function, you can use the HasLowerBound (x) function to test if the range will have a Minimum before taking the Minimum.
