Constructors

Avg()

Initializes a new instance of the Avg class with name "Avg" and variable parameter count (minimum 0).

public Avg()

Methods

Run(List<object>)

Calculates the arithmetic average of all numeric operands. Each operand is converted to double, summed, and divided by the count. Returns NaN if no operands provided.

protected override object Run(List<object> items)

Parameters

items List<object>

List containing zero or more numeric operands to average.

Returns

object

The arithmetic mean of all operands as a double, or NaN for empty lists.

Exceptions

FormatException

Thrown when any operand cannot be converted to a numeric value.

DivideByZeroException

May return NaN when dividing by zero operands.
