The SUM function takes one or more numeric parameters, adds the values of each, and returns the result. This function may be called in an integral number, decimal number, or string context. The data type of each parameter in the numeric contexts will match that context. In a string context, the function will treat its parameters as decimal numbers, though integral numbers may be provided.
