Syntax
The SCAN function syntax has the following arguments and parameters:
initial_value
Sets the starting value for the accumulator.
array
An array to be scanned.
lambda
A LAMBDA that is called to scan 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.
Tip
Before using this function, you need to turn on the allowDynamicArray option
Basic Usage
Create a list of factorials
