REDUCE function
Reduces an array to an accumulated value by applying a LAMBDA to each value and returning the total value in the accumulator.
Syntax
REDUCE(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 reduced.A1:C2 |
| lambda | Yes | A LAMBDA that is called to reduce 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 REDUCE
Apply a sequence of changes to an opening balance
=REDUCE(B2,A2:A4,LAMBDA(balance,change,balance+change))Starting at 100, the running balances are 120,115,125. REDUCE returns only the final balance 125. SCAN can return the intermediate balances as well.
