{{getLoggedInUser() == undefined? getMsg('unknownUser') : getLoggedInUser()}}
Computes the nth smallest element of a field or array.
You can also give a condition which records to include.
NthSmallest( n, fld ) NthSmallest( n, fld, condFld ) NthSmallest( n, fld, condFld, cond )
| n | index of which largest element to take. |
|---|---|
| fld | The name of a field or array variable whose elements should be used to calculate the nth smallest element. |
| condFld | The name of the field that groups the elements of fld. (if fld isn't an array). |
| cond | A string declaring the type of grouping to be used on condFld. This only makes sense for groups based on Date, DateTime, Time, and Boolean fields. See Summary Field Conditions for a list of strings you can use here. |
A number.
// returns the n<sup>th</sup> smallest element of the array nthSmallest(4, [2,5,3,2,9,6,4,3,2,5,7,8,5,1,3,6,4]) //returns 2
// returns the n<sup>th</sup> smallest element of the database field
nthSmallest({Sales.Sales_Amount})
// returns the n<sup>th</sup> smallest Sales_Amount grouped by Vendors
nthSmallest({Sales.Sales_Amount, Vendors.Vendor})
// a formula that depends on the n<sup>th</sup> smallest element of Sales_Amount
numberVar nth = nthSmallest(100, {Sales.Sales_Amount});
if {Sales.Sales_Amount} < nth then
