FACTOR(6) Games Manual FACTOR(6) NAME factor, primes - factor a number, generate primes SYNOPSISfactor[ number ] ...primes[ start [ stop ]] DESCRIPTION Thefactorutility will factor integers between -2147483648 and 2147483647 inclusive. When a number is factored, it is printed, followed by a ``:'', and the list of factors on a single line. Factors are listed in ascending order, and are preceded by a space. If a factor divides a value more than once, it will be printed more than once. Whenfactoris invoked with one or more arguments, each argument will be factored. Whenfactoris invoked with no arguments,factorreads numbers, one per line, from standard input, until end of file or error. Leading white- space and empty lines are ignored. Numbers may be preceded by a single - or +. Numbers are terminated by a non-digit character (such as a newline). After a number is read, it is factored. Input lines must not be longer than 255 characters. Theprimesutility prints primes in ascending order, one per line, starting at or abovestartand continuing until, but not includingstop.Thestartvalue must be at least 0 and not greater thanstop.Thestopvalue must not be greater than 4294967295. The default value ofstopis 4294967295. When theprimesutility is invoked with no arguments,startis read from standard input.Stopis taken to be 4294967295. Thestartvalue may be preceded by a single +. Thestartvalue is terminated by a non- digit character (such as a newline). The input line must not be longer than 255 characters. DIAGNOSTICS Out of range or invalid input results in `ouch' being written to standard error. BUGSFactorcannot handle the ``10 most wanted'' factor list,primeswon't get you a world record. 4.4 Berkeley Distribution June 23, 1990 FACTOR(6)
