It quickly computes any number of consecutive prime numbers using a windowing, memory efficient sieve of Eratosthenes algorithm, dumping them to standard output. They are displayed one prime per line in ascending order, unless the "twin" option is specified, which displays only twin primes, two primes per line. <p> Generates up to 18 decimal digit primes, or whatever is the number of digits of precision for a <b>long double</b> in the C compiler used to compile this utility. All numbers displayed by this utility are decimal (base 10) prime numbers. A prime number is an integer that cannot be factored. <p> A range may be specified on the command line, otherwise the starting number and the number of primes to output is prompted for. The range is <b>start</b> to <b>stop</b> inclusive, and <b>stop</b> must be greater than or equal to <b>start.</b> <p> If the <b>-c</b> option is specified, the number of lines of primes displayed is limited to the decimal count that follows this option. <p> If the <b>-t</b> or "twin" option is specified on the command line, only <b>twin primes</b> will be displayed. Twin primes are two primes that differ in value by 2. Each twin pair is displayed together on the same line separated by a space character. <p> If the <b>-p</b> or "pal" option is specified on the command line, only <b>palindromic primes</b> are displayed. Palindromes are symmetrical, they read exactly the same forward and backward. The palindromic number <b>base</b> may be specified, the default is base 10. The <b>base</b> can be any integer greater than 1. Primes are always displayed in decimal (base 10). <p> Short help is displayed when given the <b>-h</b> option. <p> <h2><a name='sect3' href='#toc3'>Author</a></h2> George Gesslein II (gesslein@linux.com) at "<a href='http://www.mathomatic.org'>http://www.mathomatic.org</a> ". <p> <h2><a name='sect4' href='#toc4'>Reporting Bugs</a></h2> If you find a bug, please report it to the author or at "<a href='https://launchpad.net/mathomatic'>https://launchpad.net/mathomatic</a> ". <p> <h2><a name='sect5' href='#toc5'>See Also</a></h2> <a href='mathomatic.1.html'><b>mathomatic</b>(1)</a> , <a href='primorial.1.html'><b>primorial</b>(1)</a> , <a href='matho-mult.1.html'><b>matho-mult</b>(1)</a> , <a href='matho-sum.1.html'><b>matho-sum</b>(1)</a> <p> <hr><p> <a name='toc'><b>Table of Contents</b></a><p> <ul> <li><a name='toc0' href='#sect0'>Name</a></li> <li><a name='toc1' href='#sect1'>Synopsis</a></li> <li><a name='toc2' href='#sect2'>Description</a></li> <li><a name='toc3' href='#sect3'>Author</a></li> <li><a name='toc4' href='#sect4'>Reporting Bugs</a></li> <li><a name='toc5' href='#sect5'>See Also</a></li> </ul> </body> </html>
