The # original version was published in Cody and Waite, Software Manual for # the Elementary Functions, Prentice-Hall, 1980. The present version has # been modified to operate correctly with IEEE floating-point arithmetic. # It will malfunction on many CRAY and most CYBER systems, however. See by W. J.
