This function reduces an array to an accumulated value by applying a LAMBDA to each value and returning the total value in the accumulator.
REDUCE([initial_value], array, lambda(accumulator, value))
This function has the following arguments:
Argument | Description |
---|---|
[initial_value] | (Optional) Sets the starting value for the accumulator. |
array |
An array to be reduced. |
lambda |
A LAMBDA that is called to reduce the array. The LAMBDA takes two parameters: accumulator: The value totaled up and returned as the final result. value: The calculation applied to each element in the array. |
If an invalid LAMBDA function or an incorrect number of parameters are provided, it returns a #VALUE! error called "Incorrect Parameters".
Returns a numerical value.
REDUCE(, A1:C2, LAMBDA(a,b,a+b^2))
REDUCE(1,Table2[Nums],LAMBDA(a,b,IF(b>50,a+b,a)))
This function is available in product version 15 or later.
