Power to him! A reminder that for efficient really high precision arithmetic, INTEGER arithmetic is needed. Setting up the hardware so that easily programmed exact integer arithmetic, preferably using units such as long, longlong, etc., would simplify the handling of these problems. There would be little added cost in providing these capabilities as well. -- Herman Rubin, Dept. of Statistics, Purdue Univ., West Lafayette IN47907 Phone: (317)494-6054 hrubin@l.cc.purdue.edu (Internet, bitnet) {purdue,pur-ee}!l.cc!cik(UUCP)
