series_divide()

Applies to: ✅ Microsoft Fabric ✅ Azure Data Explorer ✅ Azure Monitor ✅ Microsoft Sentinel

Calculates the element-wise division of two numeric series inputs.

Syntax

series_divide(series1, series2)

Parameters

Name	Type	Required	Description
series1, series2	dynamic	✔️	The numeric arrays over which to calculate the element-wise division. The first array is to be divided by the second.

Returns

Dynamic array of calculated element-wise divide operation between the two inputs. Any non-numeric element or non-existing element (arrays of different sizes) yields a null element value.

Note: the result series is of double type, even if the inputs are integers. Division by zero follows the double division by zero (e.g. 2/0 yields double(+inf)).

Example

Run the query

range x from 1 to 3 step 1
| extend y = x * 2
| extend z = y * 2
| project s1 = pack_array(x,y,z), s2 = pack_array(z, y, x)
| extend s1_divide_s2 = series_divide(s1, s2)

Output

s1	s2	s1_divide_s2
[1,2,4]	[4,2,1]	[0.25,1.0,4.0]
[2,4,8]	[8,4,2]	[0.25,1.0,4.0]
[3,6,12]	[12,6,3]	[0.25,1.0,4.0]
