Shareware developer Bob Delaney has created a Carbonized version of his multi-precision RPN scientific calculator that runs under both Mac OS X and 9.x (with the CarbonLib extension).
“MPCalc makes it easy to generate and manipulate large numbers, large in both length and magnitude,” Delaney told MacCentral. “It can handle numbers with up to 30,000 decimal digits. It can also handle numbers whose absolute values lie between 10^-161614210 and 10^+161614210.”
MPCalc, which is free, now has over 40 scientific functions. It can be
downloaded from the product Web site. The popup menu selects from three keypads. MPCalc was programmed in C++ and is based on
Victor Shoup’s NTL.
