SCAN function
Scans an array by applying a LAMBDA to each value and returns an array that has each intermediate value.
Syntax
SCAN(initial_value, array, lambda)Square brackets indicate optional arguments.
Arguments
| Argument | Required | Meaning |
|---|---|---|
| initial_value | Yes | Sets the starting value for the accumulator.1 |
| array | Yes | An array to be scanned.A1:C2 |
| lambda | Yes | A LAMBDA that is called to scanned the array. The LAMBDA takes three parameters: 1.The value totaled up and returned as the final result. 2.The current value from the array. 3.The calculation applied to each element in the array.LAMBDA(a,b,a+b^2) |
Try SCAN
Show every intermediate running balance
=SCAN(B2,A2:A4,LAMBDA(balance,change,balance+change))SCAN applies +20,-5,+10 to opening balance 100 and returns each updated balance. The opening value itself is not an extra output row.
