Prime Number Generator--this utility will interest you if you like to work with prime numbers. It has two modes. Mode A finds primes starting at a number of your choice. Mode B finds all primes between a start number and a stop number. A "Stop" button has been added so that you can stop building the table if you make a mistake or change your mind. You can see the table change as it builds with the table scrolled to the bottom. The table now displays the index and prime numbers with comma separators. Both fields now go up to 9,999,999,999. You can select information in the table for copying to an application or file.
