- (String) to_x12(truncate = true)

While the ASC X12 standard supports the usage of exponential notation, the HIPAA guides prohibit it. In the interest of simplicity, this method will not output exponential notation, as there is currently no configuration attribute to indicate if this is allowed or not -- if this is required in the future, the best place for it to fit would be in SimpleElementUse
