    Key Outcomes

    By leveraging these simple math transform functions, ServiceNow customers can efficiently process numerical data, enhance their workflows, and generate meaningful insights from their data sets. Proper application of these functions ensures accurate calculations, facilitating better decision-making based on real-time data analysis.

    Use simple math transform functions to perform basic mathematical calculations on Number data pills.

    Simple math transform functions require an Array.Number, Array.Integer, or Array.Decimal input data pill. Make sure to use the correct input data pill type when applying simple math transform functions. If a simple math transform function is applied to an improper data type, the data is not transformed at runtime and the input value is returned instead. For more information on confirming your flow runtime values, see Test a flow.

    Absolute Value

    A mathematical function that returns the distance from zero for any real number. An absolute value is always a positive or zero value.

    Input data pill Output data pill
    Number, Integer, or Decimal Number as the absolute value of the input number

    Average

    Returns the average value of the elements in the input array.

    Input data pill Output data pill
    Array.Number, Array.Integer, or Array.Decimal Number as the average value of the input array.
    Figure 3. Example
    • Input: [10, 30, 20]
    • Output: 20

    Count

    Returns the number of elements in the input array.

    Input data pill Output data pill
    Array.Number, Array.Integer, Array.Decimal, Array.Object, Array.String, or Array.Boolean Number of elements in the input array
    Figure 4. Example
    • Input: [2, 10, 30]
    • Output: 3

    Divide

    Divides the input value by a given value.

    Input data pill Parameters Output data pill
    Number, Integer, or Decimal Number to divide the input value by. Number as the division of the input value by the parameter.
    Figure 5. Example
    • Input: 12
    • Parameter: 4
    • Output: 3

    Max

    Returns the highest value found in the input Array.

    Input data pill Output data pill
    Array.Number, Array.Integer, or Array.Decimal Number as the highest value in the input Array
    Figure 6. Example
    • Input: [1, -5, 20, 6]
    • Output: 20

    Median

    Returns the median value of elements in the input array.

    Input data pill Output data pill
    Array.Number, Array.Integer, or Array.Decimal Number as the median value of the input array.
    Figure 7. Example
    • Input: [10, 30, 15]
    • Output: 15

    Min

    Returns the lowest value found in the input Array.

    Round

    A mathematical function that approximates a numeric value based on rounding rules and a digit position. The function rounds up by adding one to the digit to be rounded and then replacing all digits to its right with zeroes.

    Note:
    The function uses the digit to the right of the parameter digit to round up or down. If the digit to the right has a value from zero through four, the function rounds down. If the digit to the right has a value from five through nine, then the function rounds up. If there is no digit to the right, then the function rounds down.
