series_subtract()

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

Syntax

series_subtract(series1, series2)

Arguments

  • series1, series2: Input numeric arrays, the second to be element-wise subtracted from the first into a dynamic array result. All arguments must be dynamic arrays.

Returns

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

Example

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_subtract_s2 = series_subtract(s1, s2)
