The name of the function.
public static readonly string FunctionNameProperties
Gets metadata describing the function's category, description, and argument structure.
public override FunctionInfo FunctionInfo { get; }The function info as FunctionInfo.
Overrides:
When true, FunctionBase automatically evaluates this function element-wise over any multi-element array argument and returns a spilled array result. Override to true in pure scalar functions (e.g. ABS, LEN, MOD) where applying the function independently to each element of an input array is the correct dynamic-array behavior. Leave false (the default) for reducers.
